Basically users can go up in the hierarchy and get permissions to edit (others)questions, flag them, edit (others)answers, create new tags(new users can not create tags, in order to have everything in check, there are some tags and then when they get more score, as an indication to their experience level they can create new tags), etc, and they are all automated. this really helps with the community management chores imho.
And by the way, Instead of using the users username, in questions and answers and pretty much everywhere, I guess this should be their names rather than their usernames, this makes it possible that users can change their names(nicknames) without the need to change their usernames, this is the also the case, when users use Open-Login to register, when they do, there is no way to change the username which is displayed everywhere!
And like wordpress, it would be a great idea to have an automated backup that would back up the database, or site files, to googleDrive or dropbox or etc.
