It's well understood that there is to be no selling/trading/advertising within the vogons boards, but what about a thread with just member's eBay/amibay/whatever user names? A lot of us would feel more comfortable buying and/or selling to other vogoners but would prefer to do it under the umbrella of a sanctioned and safe selling site.

Would a thread listing only usernames for others to browse be acceptable or does that still fall under the no transactions rule?
