We do have a global search where you can find other groups and previous threads on various topics. Some of these topics you mentioned will likely be behind the Pro membership and won’t come up in a search, but those items you brought up would be well suited to the Pro forums that are more private and medical focused.
As for moderators, we always welcome members of the community in helping us grow and manage this community.
We actually don’t have a lot of spam/scam, which is very nice, so there isn’t as much to report, but that is often the first line of defense.
The other big help is just adding content, replying to other members, answering questions, and generally just helping the community back.
