Quarxnox

It's a good tool for moderation, but it would be nice if you could customize the text that it displays. "you do not have enough posts..." is sort of cryptic and not the best for letting users know that it's for moderation. Also, easily hackable by replacing 'avatar' or 'personal' in the url with 'edit'.

It is an awesome plugin that safe forums need. I wouldn't be able to make mine safe without it. Unfortunately, it doesn't check to see if the user has permissions in the approval function, and is easily hacked from the javascript console.
