We've recently added some some new features to the AppFuse project. The first feature is the good folks at Mark Logic (primarily Jason Hunter) has setup a kick-ass mailing list archive for us at appfuse.markmail.org.
This is an easily searchable set of archives and goes all the way back to when our mailing list started in March 2004. In the future, they hope to provide RSS/Atom feeds and allow posting (like Nabble does). I've added a link to these archives to the mailing list page. To learn more about MarkMail, please see Jason's announcement of the service @ Apache.
