The betting system in CS:S is pointless anyway. There is an economic stimulation plugin already in place, and there isn't really a lot of need for lots of money on the servers, since awps are restricted to 1 per team, and there isn't anything more expensive than that (that is used widely, apart from the autosnipers which are for noobs anyway).

Also having FF on would just cause loads more grief. It's kiddy, sure, but you should see some of the lamers that are in the pubs :|
