Noticed this today, but I don't think people should be able to edit posts in their blog. I think deleting should be an option, but to outright change what a person says is wrong, IMO. I mean, yeah, I guess it does say "post edited by so-and-so" but why not just make the option to delete and keep people from doing the passive-aggressive nonsense?
Yeah, I noticed this a while ago. I don't see any reason for it to be enabled (just today, it was abused in this blog), as deletion/reporting of comments is handled separately. It's a simple permission switch and can be disabled without affecting anything else.
