Please join the buildbot users mailing list to be notified about new releases and to discuss how to configure and use the Buildbot with other users. Some folks find the Gmane archive easiest to browse.
The #buildbot channel on Freenode is also actively used and is a great place to get a hand with your configuration (if you do not know what IRC is or you do not have an IRC client installed, you can use webchat). IRC logs are available online here.
Since Buildbot is a developer's utility, we get a lot of patch submissions. See SubmittingPatches for instructions.
