Yeah, TLDRLegal is actually older than ToS;DR, and I noticed that the community there kinda stagnated because editing was so difficult. I don't know what happened to them after they got their 10k from indiegogo, but I think they're still around. The idea of "managers" is to keep an authority reviewing the content since legal info is sensitive and can be very impactful to people, but TLDR admins can always transfer management from one person to another.
