I can think of a reason to be able to edit posts, at least in one forum. If someone is selling a list of items, it is helpful to be able to edit that post as things ar sold rather then make a new post saying what is still available and what not. Keeps things nice and orderly :beige:

Also, If someone edits their post it usually makes a note of it at the bottom of the post stating the date and time it was edited unless the person edits something within a minute or two of posting.
