We had an issue with three AFKer's this afternoon that no admin would kick.

They kept dying on Mines of Moria, and then sat on Spec on the other maps until the auto-balancer set them onto a team.

I'd be interested in setting up a script to allow people to challenge AFK players with a prompt that would kick them if they didn't respond. So, a player wishing to challenge would do a !afkchallenge (or whatever the command will be called). It'll prompt the person with a list much like the !votemute system. Instead of other's being asked to vote, it would only ask the person to respond Yes or No if they're AFK or not (like the !votemute menu).

If they don't respond with a minute or two, the person gets kicked by the server. Either response will allow them to stay, so a smart ass on Spec won't get kicked.
