advise messenger for Linux

pidgin, empathy. both are Multiprotocol in General is good. empathy has a terrible interface by default, both gtk and qt — kopete

I use qutim+skype for linux

pidgin
keeps ICQ, jabber and Skype. via jabber you can and mail agent to pick up.

also use qutim

Also enjoy qutim Still Naur form qip 2010 works through wine but it is certainly not Uniswa :))

gajim.

And Skype is still better to use off the client.

also use Glyco qutim'ohms just because pidgin/emptathy have a very comfortable and usable interfaces that cannot be treated with plug-ins. Here you can configure Kopete to a comfortable state — but he's QT and draws too much KDEшных dependencies. Tried it yet mdc.ru/ — interesting idea but still something of me in him was not satisfied. Also not satisfied with Instantbird.
Still Licq is not bad but it looks too ancient.
