Okay, so I had an answer on this question here. In that answer I referenced Chip's answer. The reason I mentioned his answer is because one of those plugins (Role Scoper) is a fine alternative if the OP prefers the interface. However, in my experience, the plugin I suggested is the 'right' one for the job - most frequently and recently updated, greater flexibility, better RTL language support, etc. The moderator (EAMann in this case) removed my answer and made it a comment on Chip's answer instead, ensuring that I can't get answer or upvote credit for what (in my opinion) is a better solution. I'm not normally one to question the mods, but I don't understand why an answer that is standalone "should be either an edit to or a comment on" another user's answer.
Not trying to throw a tantrum, just trying to follow the logic and requesting insight so I don't make the same mistake again.
