My preferred way of messaging is using XMPP (previously known as Jabber); my Jabber ID is firstname.lastname@example.org (this is NOT an e-mail address; sending e-mails to this address wont work). Free software XMPP instant messengers include Empathy (POSIX) and Pidgin (cross-platform).
You can also reach me by e-mail. My e-mail is .
