I have an unfortunately habit of (too often for my liking) getting mental dyslexia and entering the wrong bug number in comment text. So, rather than saying b*g 12345, I'll enter b*g 12344 - or something similar. (Using "b*g" so that no hyperlink will be needlessly created here.) In order to "correct" this I need to post another comment with the correction, or just leave it alone. It would be immensely helpful in terms of cutting down correction "spam" if one of the following two were possible: 1. Edit an existing comment in the database - so long as it is your own. This could perhaps be limited only to changing the bug number if people think that history / accountablity should remain. 2. Cancel a comment so that it can be entered again. (So long as people *don't* think that history / accountability should remain.) This would have the added benefit of users being able to remove their own spam / inappropriate messages from the database. 3. After entering a comment, Bugzilla could display it with an Edit / Confirm / Cancel dialogue so that the poster has a last chance to check what they've entered as it will actually appear. (Frequently when I make the mistake of entering the wrong bug number, I only "catch" it later when looking at its final hypertext form and seeing that there's a line through it - meaning that I'd referenced a closed bug rather than the open one that I'd intended.)

Dupe of bug 540 for the editing part, see bug 40896 for the preview mode thing *** This bug has been marked as a duplicate of 540 ***
