Thanks for the suggestion Jerry. This has been brought up before, but I've never settled on a great way to deal with it.
Editing restrictions are common on most forums, but I know it can be a pain.
It's mostly to keep spammers from making a post that looks fine on the first check, then going back a couple of days later and updating it with their spam.
Another issue is, it can get a thread out of whack when it gets a bunch of replies, and then the original post is changed.
In thinking about this, is it the super sort time limit that causes the most issue?
Would it be helpful to have something longer, like 8 hours or so? Or another suggested time?
