The reason I am asking is that we try and run "clean" servers for our
members and kids that want a place to play.

We ask that players not use profanity, or camp, or do stuff like
wall-hacking.  But, there are some that do anyway.

We warn them a couple of time then kick them.  If they do it again, we ban
them.

Some players will wait until they are ready to quit, unload a barrage of
profanity at some of the kids on our servers and quit before we can ban
them.

I am looking for a way to prevent this.  What would be nice is a way to log
all players that log onto a server (name, IP, CD number, time in, time out,
and conversation).  This way we could use the player info to ban the players
that do these things on our servers - even after they quit.

Any ideas?
