Would it be useful to have a table in 225, 330, or 332 (or maybe all of them) showing the differences between what an owner, maintainer, and moderator can do? Something like this, with appropriate cross-linking as necessary:
1 - While a moderator can always add existing tags, they can only create new tags or remove tags from an entry if the "Who can create new tags and add/remove tags from entries" on Manage Tags is set to Members Only, Any User, or to a Custom Security Group that contains that moderator.
2 - When a moderator screens a comment that comment is collapsed but a link remains for the moderator to unscreen the comment. If they refresh the page, that comment will then be entirely hidden and can't be unscreened.
Approve or reject requests for membership (if applicable) x x x
Delete entries or comments x x
Freeze or screen comments, and see screened comments x x x
Create, edit, and delete entry tags x x x
Approve or reject entries in the moderation queue of a moderated community x x x
