Hooray - a new post from me ;-)
It always annoyed me to have 3 IM-tools constantly running (
GoogleTalk,
Skype,
Trillian for ICQ and MSN).
Up to now I'm not aware of any alternative clients for Skype.
Since GoogleTalk is based on
Jabber and Jabber supports ICQ I searched for a good Jabber client. Once I tried to integrate GoogleTalk with ICQ and took a look at
Gaim - I failed miserably loosing a lot of time - I just didn't want to try it again.
While gathering some information about Jabber I stumbled over
Psi.Setup for GoogleTalk was no problem - the Wiki at the Psi-Homepage provided detailed information.
Biggest problem was to find a Jabber server supporting ICQ - every list I found (jabber.org,
xmpp.org) provided no details about supported transports. After reading some forum and blog posts I got the impression that everyone who is using Jabber runs his own server.
Now I'm using
jabber.belnet.be. Seems to be a reliable service.
The greatest pain during the transition was caused by the ICQ contact list import.
Every contact required several mouse clicks - for every contact you get an event stating that the user xyz wants to be authorized -> Clicking add/authorize -> waiting -> next event with the confirmation.
I also had to group and rename all contacts - the configuration of my Trillian was local.
Unfortunately the hover help on a contact does not reveal icq user information -> right click / user info is needed :-(
