First, let me thank you for providing this service and for keeping m0n0wall/smallwall alive!
The main reason I (and probably everyone else who is happy with m0n0wall's feature set) upgraded to smallwall was to have a security-supported system again. By "security-supported" I mean that when a security-critical bug is discovered in one of the components, there's someone out there who cares about it, fixes it and releases a new version.
In the "old days" of m0n0wall, I'd just subscribe to the m0n0wall-announce mailing list and get notified when I need to upgrade.
Is some similar kind of mail notification service planned for smallwall? Or does something like this already exist and I just didn't find it?
