There are three mailing lists.

boson-devel at lists.sourceforge.net is meant for users and developers. If you have questions or problems, you can always come there and ask. Note that you have to subscribe or you message needs some days to reach the list. Also include a note if you aren't on list so the other users can CC you.

boson-cvs at lists.sourceforge.net is only meant for CVS logs, please do not post there.

boson-bugs at lists.sourceforge.net is also not meant for posting, bug reports are sent there. See below on how to report bugs.

You can subscribe and unsubscribe them here.

We also have an IRC channel. If you have questions/problems/compile errors, you can just go to #boson on openprojects (e.g. irc.kde.org).

You can report bugs using KDE's bug tracking system or the 'report bug' feature in boson's help menu.
