Additions For Lesane's Store Hack
 

How about letting you edit somebody elses post, or post as them once?

Or the ability to use one of those jive-translaters, or any of those translaters that turn what you type into some slang dialect, on somebody elses post?

Are either of these possible? If so, I'd love it.

as admin or mod you are able to edit someone else posts..

Yeah, but I was thinking of something in the Store that users can buy that allows them to edit another's post.
