Setting up RPG Server looking for some insight HELP PLZ!!

Hey Folks

So as the title suggests we are setting up an RPG/PVP server. We have everything in place, except one thing, a faction mechanic.

We started looking at Factions, then decided towny was best. What we want to do, using towny is to have 4 predetermined towns (the factions). Players who join will then choose which town they join.

Now this in itself is fine. Problems arise when new players join and want to join a town but the mayor (owner of the town) isnt around to invite them, so they are then left either factionless (not something we want) or forced to join those towns who's mayor's are online.

So the real question is: Does anyone know how to implement an auto add function to place a player within a towny town, such as clicking a button or similar?

If this is possible using other plugins, we are willing to adopt those, it's just that towny seemed to be the best, and has great functionality with things like dynamicmap.

Thanks for taking the time to read this, all suggestions greatly appreciated.
