If you are using fedora+emacs and constantly use jabber for chatting .. you will love emacs jabber. As posted last time, I am using it since then and it is wonderful. Now I have both erc for IRC and emacs-jabber for gmail on my programming editor. 😀 Last week I had posted a review at emacs jabber . In case you are using fedora 11 try out the rpm here.
I use gmail for chatting and my configuration options are:
(setq tls-program '("openssl s_client -connect %h:%p -no_ssl2 -no_ticket"))
(:connection-type . ssl)
(:network-server . "talk.google.com"))))
You may like to check emacs-jabber/jabber-gmail.el for setting up email notifications also.
