I don't think this has been brought up yet (?) but a useful feature on some sites: if someone replies while you're in the process of typing your own response to the same question, a notice pops up when you hit 'add', so you can see it. It then allows you to alter your answer if it's now become redundant, or there's something you want to add/revise in view of what the other person said. Less frustrating, more concise and cuts down on multiple posts from one person in a short period. One final wish, as this reply illustrates: it would be great to be able to break a comment into paragraphs, so different points weren't all jammed together in one big, hard-to-read block of text. Pretty please?
