There's this game that I joined as a lurker but eventually decided not to join that I can't get rid of. I've clicked the button to remove it from my list multiple times but it repeatedly keeps coming back to haunt me. Anyone know how to remove it for good? Seeing red numbers, being happy and then annoyed when I see that its that game again has gotten annoying.

You have to tell the GM that you no longer wish to be a lurker and wish to be removed from the game.  Give 'em a week, and if they don't remove you, you then contact the Admins and they'll help out.
