So we're going to try something new this year. I don't know how well it's going to work, but we'll give it a shot: The Darkover Game Trade and Sale Table. Here's the skinny.
There will be one (maybe two if there's enough interest) table set aside with a stack of index cards. Place your game on the table, along with an index card with your name, a number where you can be reached for the weekend (in case you're not in the game room), and a preferred sale price and/or game(s) you would like in trade. If someone sees something they want, they find you, you negotiate the details, and everybody walks away happy. Whatever of yours is still there at the end of the weekend, you take home.
(Of course, if people want to start negotiating trades before the Con, why look, here's a perfectly usable space... :) )
IMPORTANT NOTE: The Darkover Grand Council Meeting, the Armida Council, and the Staff of the Game Room WILL ACCEPT NO RESPONSIBILITY for trades, sales or other exchanges conducted through this function. We're all big boys and girls here, let's deal with each other as such.
