Regular group members can edit their posts up to the specified period of time (usually 30 minutes) after they posted their forum post. After that they can't edit it anymore. I think this is correct. Once you edit a post and it has been sent to the subscribers of the forum, they won't get an update anymore. Furthermore, if someone else responds to your post and you change it, the discussion could be compromised.
