Okay, time to expound a bit...

1. Not interested in collecting singles - You're correct, I'm first and foremost a set collector/builder, but have accumulated a reasonable collection of singles over the past two years as well. Far more than I anticipated when I began, to be honest. I primarily hang out at PokerChipForum.com (ChipTalk has fallen into a bit of disrepair over the past few years; the vast majority of active set-builders and custom chip enthusiasts have moved to PCF) although I do check into TCB once or twice a day. Because of this, the number one reason to not join that I receive from folks I talk to about the club is that they simply aren't interested in collecting singles. Fair enough.

2. Outdated software - The question was posed why this matters, or what benefits would modern forum software have over the status quo. Fantastic question, and there's a number of good answers.
- Easier formatting. This is a perfect example. If i want to make a list here, I'd probably have to break out some HTML code. Modern forum software allows for formatting of bulleted lists and other such things much more easily.
- Batch photo uploading. Rather than choosing 1 photo, uploading it, choosing another, uploading it, etc, I can select 5-10 photos at a time. This saves a bit of time when composing a post.
- Quoting specific sections of posts is much, much easier in modern forum software - particularly when wanting to batch-quote.
- Division of content. These days many folks want to drill directly into the content that suits them. More modern software allows and encourages posts to be generally categorized. This actually matters quite a bit as I'll get into shortly, but in general, having categories would allow for high-level groups such as General Chipping, Classifieds/Auctions, Off-topic, and/or a Politics & Religion subforum.
- A number of other major clubs, groups, and associations dictate that if you want to talk about religion or politics on the forum, you *must* do so in a separate sub-forum, and never was that so important as with the contentious 2016 presidential election. Some groups even go so far as to make its users apply to post there and acknowledge that there's a different set of rules in that subforum. Other groups simply say any such discussion is disallowed and provide no space or tolerance for it. The point is, this content can be divisive, is almost always off-topic, and frequently non-inviting to new participants. Having more modern software would allow such topics to still be discussed, but maintained in a space where people have to *want* to see it/participate in it.
- Sortable classifieds adds. Some forums offer classified sections that allow you to designate your post as a "For Sale" or "Wanted" post, and you can select to only see each variety if you so choose. Some also offer a "Trade" category.
- Feedback/trader ratings. For folks new to chipping it may be beneficial to see trader ratings on individual users, somewhat similar to eBay's ratings. This is particularly handy since you don't have to be a member of the CCA to post here, which means not everyone who posts here is bound to the ethics standards of the CCA. If someone is looking at dropping a few hundred dollars on chips in a private party transaction, having member or trader ratings & history may provide someone the confidence necessary to pull the trigger (or provide them caution enough not to).
- The ability to block users. Sometimes there are folks that you know you simply aren't interested in what they have to say. Modern forum software allows users to block other users, thus making that content invisible to them.
- Lists of newest threads, classifieds and posts. If you prefer to see the top 5-10 most recent additions, some forum software allows for that.
- Visual indication of new threads or posts. Some folks here have tossed around the suggestion to search for *New* or something to that effect in order to find new content. In most modern forum software, there's a visual indication next to every sub-forum and thread that indicates if there's something new since your last visit.
- Private messages. Most forum software allows for users to privately message one another, and some will even email you when you get a private message if you want it to. There's also often a visual notification when you return to a forum that you have a private message waiting. This would eliminate the need for posts like "Hey David Spragg, email me please."
- Secure data transmission. If you look at the address bar of your browser, you'll likely see either "Not secure" or an image of an unlocked padlock next to the web address. That's because the forum software isn't secured, and that means an interested party can see just about anything they wanted to see clear text when posting. That also means the password you type in here is unsecure, and if anyone wanted & were so inclined they could see our passwords every time they were submitted. If you use a different password for every account & email address you have, then that might not matter much. Repeated studies show that such practice is not common, though. Some people don't give a hoot about it. Other users won't use a website that requires a password or financial data unless the site is secured/uses HTTPS.

And that's just a few potential benefits.

And since we're discussing modernizing websites, modern forum software, etc., I'll expound a bit on point #3 as well.

3. Some folks' refusal to accept PayPal/other electronic forms of payment - This is actually somewhat significant, and will become more so as time goes on. Banks & the payment industries hate paper checks and are moving away from paper items as much as possible. That means that it won't be too long until banks start charging people to accept checks for deposit. Meanwhile, companies like PayPal and Venmo allow for rapid, secure funds transmission and completely bypass the time and risk of sending a check. Even crypto-currencies like Bitcoin are starting to becoming more mainstream. Plenty of people simply won't do business with a company if they have to write a check. Heck, some don't even have checks/checkbooks! There's no reason to engage with a group of people if someone perceives them as too difficult to do business with. I won't come down on someone for wanting to do business only by check - how we take payment is our own prerogative - but we do need to at least understand that choosing to restrict ourselves exclusively to paper payments restricts some folks' ability and/or desire to engage with us.
