When you make a post, submit it, and then minutes later decide to edit, while you're editing does the post remain on the board in it's original form until you hit "submit??
I've GOT to know!
Posts should never, ever be edited. Go with your gut. What you wrote intially is what you were supposed to write. Editing the post is unfair to others who then will not have a chance to see what you orignally wrote.
I would never consider editing a post myself unless it was for spelling, content or clarity of thought. It would be good of you to follow that example!
