I found www.mibbit.com website that let me to use irc , but I don't know how can I use it
for example , what is this ?
I want to know simple way to use irc .
There several useful information about IRC in this thread.
Take a look at it, and let us know how it goes.
Just grab a irc client from a pool of choices and get started .
You can start with Xchat which a popular irc client .
If forsubhi is a Kubuntu user as per his profile then I think konversation would be better than XChat.
Personally I prefer KVIrc but konversation is a little simpler to set up and use.
