Best IRC-client i've used on Linux. But it won't beat mIRC... And i found this little bit confusing to setup/modify but like i said the best i've tried on Linux.
used this in Linux Mint 16 MATE 64bit (Petra)
the best i've ever used, i would personally thank the team that made this if i could
Thanks to my core, favorite IRC client
Quassel is like putting a 777 cockpit in a soccer moms mini van. Way too much going on and 95% of it you dont need.
My favorite IRCc client. Many great features and cross platform.
