now give prayer to the great lord chuck tingle, that your own butt might be lovingly pounded by the game invite you so desire.

(seriously, though, anon upthread is right about asking on the mod plurk, if you don't know anyone in the game. i'd personally see if they have a tdm first - some private games do, to vet newbies or give them a chance to see if they mesh with the players - just because private games can be a bit of a crapshoot, especially if they're locked.)
