Just a few things to keep in mind:
1. We're all friends here, so be honest and don't try to snowball anyone.
2. We see each other with some form of regularity, so this might seem kind of a silly forum; however, if we're in between tournaments and won't be meeting for a time, you can post your wants here and work out a deal; that way you can make the deal when we meet next, or set up a meeting amongst yourselves and do it that way.
3. Using PM or email as a way to contact each other when trying to make a deal is preferred; that way it doesn't clutter up the board and you can keep the details to yourself. You can use the board to say something like "I want your X, and I have X...email me/PM me to make a deal" or something similar; just don't do your entire transaction on the board.
4. Try to limit yourself to one thread of your haves/wants; whenever you need to update the lists, just edit your post and add the new cards. You can start a new topic for updated lists, but if you do, please delete the old one; this reduces board clutter.
5. Please make sure to post both your want list and have list; posting one or the other by itself is incredibly annoying and doesn't really help anyone.
6. You may also offer to sell cards in this forum; if you do this, make sure to post the amount you want for each card you list; if you don't know what you want for it, just say "best offer" or something.
7. This "rule" has changed, because, dammit, I need cards too!
8. Have fun, and don't snowball anyone.
