I have been looking around and can not seem to find a MOD for Instant Messaging. I have recently implimented the PM Pager and Private Messaging, but these are still not Instant Messaging (pop up window chat back and forth). Are there any MOD's that can do this?
Such a MOD hasn't been released yet. The closest you'll get is either, as you stated above, the PM MOD (with PM Pager) or a Chat MOD such as the ConquerChat.
