Translations: itMailing List
There is a mailing list where you can ask for info and follow the discussions about the meeting. It is mostly in italian but feel free to ask questions in english.
IRC
There is also an IRC (Internet Relay Chat) channel where discuss and chat with other participants: connect to server irc.autistici.org and join channel #hackit99 (again, it will be mostly in italian, but english speakers are welcome).
If you prefer XMPP/Jabber, you can reach the same channel as room #hackit99@mufhd0.esiliati.org (please include the hash)
