I think you are going to have to ask Bill about this one. I do not think that editing is allowed after a certain amount of time but that is just a guess. I would go back and see if I had a button myself but we have different tools as a moderator so it wouldn't apply. Sorry if i couldn't give you a better answer. Anyone other mods care to chime in?
