General Mailing List
The general mailing list can be found as a Google Group or as a plain old mailing list at exemplar-project@googlegroups.com. This mailing list is the place to ask questions about Exemplar or ask about bugs or discuss upcoming features.
Activity Mailing List
The activity mailing list is only posted to by automatic processes. The Subversion server, issue tracker and automatic build scripts all post to this list informing you of changes in their state. This list is probably most useful to developers but if anyone wants to keep an eye on how busy the project is, here is the place to look. The list is available as a Google Group or as a regular mailing list at exemplar-activity@googlegroups.com.
