Ok, if you click on, say, my smilie face, a small box will appear and ask you if you approve of my post on this thread. You can 'approve' or 'disapprove', and then you can list a comment either way (that part is optional). The more 'approvals' a person gets, the better for them. A bunch of 'disapprovals' sets off a 'flag' on the poster and they get warned. A bunch of warnings will lead to banning.
Oh, and you can't give yourself extra points................
How's that???
