Funpidgin is a modified version of the Pidgin instant messenger application. It was made in response to the controversial auto-resizing textbox that was implemented in Pidgin. Current features of Funpidgin include manual resizing and the ability to turn off persistent window placement. Funpidgin's releases are meant to coincide with Pidgin's releases.
IM-Filter is a daemon that runs on a firewall and filters ICQ traffic. The daemon can identify file transfers, handle UIN and word blacklists, manage a list with currently logged in users, and log messages sent via the ICQ protocol. The modular design allows implementation of other protocols like MSN or IRC.
