Does Savannah have any policy/system in place for removing projects or users that are inactive?
No. Also, I'm not sure "inactive" is the right criteria for any deletion. A "nonexistent" project which has never had a commit or any other substantive content would make sense to me to delete. Otherwise, I doubt it. I hope to write more about this later today. As for users, I see no criteria to apply. Maybe after a few more years we could say "hasn't logged in in 20 years", but even 10 years seems too aggressive to me :). I'm crazy I guess ... k
