It's absolutely fine to edit your post; however, you need to provide advice on the modifications you have made

"Scratchpad: View, Edit, (Private: View, Edit)".

tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
