I was wondering why you can't modify or delete a comment that you post here,after a short while. Sometimes you misspell a few words or wrote something that someone took offense to, and you want to rectify the situation, yet you can't do so. If you were the one that posted the comment, why shouldn't you be given the opportunity to fix it, especially if it may have offended someone, or for any other reason? On FT for example, you can always edit.
