After using ICQ exclusively since it was still Mirabilis and not some AOL-appendage (I still have an 8-digits number starting with a 5), I finally came around and registered a second IM account. You can now IM me as

AKK (54426950) on ICQ and/or as
AKK@jabber.hot-chilli.net using the XMPP protocol (Jabber).

I'd like to add that jabber.hot-chilli.net allows message exchange with other services.
