Another suggestion: do you think we can get a "delete" button to erase past posts that you may be ashmed of or so that the 'edit stain' will not show up when editing?
Do you not have this icon on your posts?

That lets you kill your post.
You should also be able to edit a post (that you've written) with the button just to the left of it. I think... I'm still learning this software a bit.
I don't think this software leaves edit stains, either. It's different than what was used at the PTA board.
