Feel free to delete this thread if it's completely useless.
I just remember a lot times when I were at school or somewhere else and wanted to go at #nfs. The problem was that since the provided client here is a java one, this required me doing java updates/unblocking stuff and takes much more time (most likey PC's in school have limited access to this). I know most of you guys use mIRC or another client.
Since I used Mibbit time ago and I still use to chat on few IRC Channels, here is the Mibbit client widget
I use when I most likey at school.
Again, considerate this just as a suggestion :)
