I wasn't talking about people who don't reply for a day or two, or even a week or two. My complaint was against those who never reply. It was mentioned in an earlier reply that it could be caught in a spam filter...I'll admit that one didn't occur to me. I usually give the emails a subject heading of "Let's Trade" or "Chips wanted" or things along that line. And as Debbie mentioned, I'll always send a quick email to let people know that I've received their chip(s). It's so easy being courteous to fellow collectors that I'm amazed that there are those who can't seem to be bothered.
