Mailing Lists
There are several lists used for communication among Mule users and developers:
Users list: enables Mule users to share knowledge about configuring Mule, using the Mule APIs, etc.
Developers list: enables developers contributing code to the Mule project to share knowledge
Issues list: provides read-only notifications about Mule issues in JIRA
Builds list: provides read-only notifications about Mule builds
Commits/SCM list: provides read-only notifications about code commits to Mule
Announcements list: provides announcements about Mule, Galaxy, and MuleForge projects
You can go to http://xircles.codehaus.org/projects/mule/lists to manage your subscriptions. You can also view and post to these lists through the MuleSoft forums. There are also several sites that provide searchable archives of the Mule discussion lists, as described below.
