I've written a smallish epic4 script that basically makes epic4 a lot easier to handle and has some useful keybindings. I'm currently not working on this much as I've not found much need to recently. I used to use it day in and day out to keep in touch with people and have found it to be stable. Development has been stopped on this as I now use irssi as my IRC client.
The current available version is 1.98 and can be downloaded from here.
