playBunny: We've had this same thing pointed out in the wording of whether or not you will have invitations sent out or rated games in a tournament that you're creating. Since you have Pawn membership and can't create tournament, I'll tell you now so you won't be confused when you become a paying member and are able to create tournaments. You may view tournament pages and are allowed to join one tournament, right? Go to a waiting tournament page. you'll see the column with the various parameters that the creator can choose from. The two that have the convoluted speach I'll paste here:

Unrated games (no BKR will be affected by this tournament): no
Private tournament (you will send personal invitations): no

I bet you'd word these sentences differently being the English speaker that you are, wouldn't you?
