I think we use Reverb as our current in-game chat platform?
Its pretty buggy, especially the Monarch Recruiting chat.
I'd like to suggest a different chat platform for in-game and perhaps it can facilitate interkd chatting as well for diplo?
Its called BlaB! and is built on php/Ajax

It's quite lean, easy to manage but also has extra features that can be turned on/off.
There is only a small lifetime license fee and the source code can be modified to suit our needs.
Perhaps the admins can take a look to see if this is something worthwhile to implement for Utopia or not?
