Mixing a community configuration page, and list of action items to handle on the same page might be a bit much, and will be more difficult to get the ux design to work.
Maybe a separate moderation page with a list of items that have been reported and need actions taken on them would be first. And then another page just for moderator configuration items for a community.
being able to re-edit markdown would be nice and like other web forum systems
Right now the results returned only contain content_text and content_html. The already rendered html is ok for display only purposes but not useful as a format for something which will be used for editing later.
Returning content_markdown as well in the result, would be more useful to front ends that want to allow the user to re-edit their original submission formatted in markdown.
A server setting to require all member account creations to be approved by a moderator/administrator before having any posting/comment provides could be an important spam protection mechanism.
