Does MozillaZine work to you? It has been dead for at least one month.This review is for a previous version of the add-on (0.0.0.2).
Mozillazine and mozdev.org
There has been a forum update lately (they changed from phpBB2 to phpBB3), but other than that it never failed me.
Net Notes will also get a mailing list, newsgroup, bug tracker and a project page on mozdev.org.
