This may have been posted already (I can't believe it hasn't), but I tried searching and I couldn't find anything, so here goes... Currently, if you edit a post, there's no indication that the post was edited. I thought it just updated the post date/time, but I just tested it and it doesn't appear to do anything at all (post date/time stays as original). It would be really nice if there was a "edited by [name] x minutes ago..." in addition to the original posting date, à la vBulletin and others. I feel that this is a crucial feature to avoid confusing or malicious/nefarious edits.
