okay, now i DO in fact support and like this idea for the sake of it being a great feature.
However, This IS a 2006 remake, clan chat was well after 2006, and in that case, makes this server a bit "out of place".
Now don't get me wrong I have my mind where features are important and my nostalgia fetish is last, but I know very well if it was added, people will give that small of a feature a reason to quit for the fact it is not 100% 2006 remake.
Hence the problem.
However i do support 100%
And irc works just as fine too.
Maybe you can ask the Dev's to make a "swift-kit" version of the game so IRC is 100% better to use.
