Scott,

If you want to go on Wednesday, you have to be preregistered and be wearing your badge.
If you want to go any other time, you must wear you badge.
The trade session is just that. No buying or selling of chips.

You just go in, and ask around for the kind of chips you're looking for.
Be sure to bring your traders with you.

I'm sure someone else will come along and correct me if I made an error, or left something out.

Make sure you know the secret word, and secret handshake before trying to get in.
