tarcellius: There seems to be reason to believe that the one-tournament-per game restriction was removed without an announcement. Also, the fact that you are currently playing two Pente tournaments is strong evidence of this, unless you were a Rook at some point in the past. I would recommend against upgrading your membership, unless you want to do so for other reasons. It would be a shame if Fencer's habit of inadequate documentation led directly to an increase in his profits.

You're listed as being signed up for the tournament in question, and (while I could be mistaken) I believe that if the restriction were in place you would have been unable to sign up at all. I expect you'll be able to play without needing to upgrade.
