"You can no longer edit or delete that post."

I hate getting "You can no longer edit or delete that post" error messages when editing my posts, mainly in the middle of a brainstorm. I wonder whether the forum admin could extend the time for post editing at all, thus giving posters more time to edit or perfect their messages. Does the forum board have a time flag for that?

This message written all at once--no (re)editing needed. More complex messages may demand more time for editing purposes.
