i dont know if you heard about, i was working on a project, an instant messaging software only for armagetron users.
has 2 parts
1-public chat- needs a server to be run, im running one right now temorary, but you could create a channel called ct chatroom , then some of you should host it .
2-private chat- allow all ppl using this software to get connected, webcam file transfer and sound functions.im sorry if you have any bugs on this private chat, it seems to not work as i expected to, but anyways its basic function- chatting- stills working at 100%

for windows users only

download armachatron here

extract and place in some folder, dont move any files from their initial location.in the pub/server folder is a server that hosts a chatroom, use it for your clan or your own channel, enjoy!

useless thing, u can use teamspeak instead of it, or just usual IM programs.

in teamspeak u cant send files, use webcam or others, and on usual im programs can u find a user called "XEvi"? i dont think so

well, in my case u will find Xevi®.C as u already know
