IRC
Please join Maemo developers and users in the #maemo IRC channel on Freenode.
Chat and Help
If you want to try out IRC then click here and pick a username when you're asked (it's not remembered or important for now) and type in "#maemo" or "#mer" as the channel. This will give you a web-based chat window using the Freenode webchat service.
Say hello and mention that you followed the link on the wiki and ask for help or just talk to us :)
Then, if you like, you can search for an irc client for your machine and dive in.
Meetings
There are regular IRC meetings of the Maemo community and representatives of Nokia on a variety of subjects. These meetings will be held in #maemo-meeting, and usually be announced on either the mailing lists or maemo.org.
Logs of these meetings are available here.
Logs
Thanks to Marius Gedminas we have logs available in chronological order.
