Thank you both, I didn't realise there was a setting where anyone who requests membership simply gets in! Changed now, no more stragglers walking in off the street :)
Pdb - I know how CC's work, been here long enough to have figured that out. But I play very little these days, and even less since the Flash version went... cos it's just a crap cartoon now with no realism at all - the ball seems to be the size of a football in the air, flying like a balloon, the sound when i hits the ground is like two pieces of wood being knocked together, and don't get me started on the avatars or the putting! The only reason I set up my own CC was to get shot pal and putter pal, which are second rate compared to the ruler I made for myself (and others) some years ago when the Cthruview overlay worked.
So there you have it, in a nutshell :)
