True about IRC - said it's a bit hard core
It's kinda the Vent or TS of IM - do you know any other instant messaging system which could support 100+ people - easily - on a single channel? Which can automatically connect servers, join your favourite channels, is highly scriptable, has dozens if not hundreds of different clients available, the list goes on?
If you use vent or TS, do you just use a public server? Because I figured out by now that the vast majority of Sins online players don't belong to clans... which beats me, would think this is the kind of MP game that requires dedicated teams and organized games!
