The #residualvm IRC channel on irc.freenode.net is also a good place to ask questions. Many ResidualVM developers hang out there regularly, as well as many ResidualVM users.

We offer forum.

Don't forget to read Forum Rules before your first post.

Don't report bugs. ResidualVM is early alpha and we KNOW it doesn't work right.

There are three ResidualVM related mailing lists. Two of them are for automated content only. The one where you can send emails to yourself is residual-devel.
