As a participant, I don't have strong feelings about this one way or another. If I were administering a Web forum, I would probably allow one hour for edits after posting. After that, changes or deletions would have to be done by a moderator. Corrections or clarifications by forum participants could be done through follow-up posts. The primary reason for this would be to maintain continuity in the threads.
I don't think it's fair to accuse people who favor time limits on editing of being out to control others or to otherwise attack their character. I think the specific personal attacks are particularly inappropriate, especially the remarks accusing a person who has not even posted to this thread of being two-faced.
