I think I've said this before, but inserting links is a PITA on POTN. Click more, find the text for "named URL" (having to read the text of every entry and understand the weird label rather than finding an image is slow), click it, paste, move the mouse to close the menu, then move the mouse to close the next menu. With most forums you click the link symbol in the toolbar, paste your url, hit enter, and you're done. It takes around 3 times longer than most forums.
Little usability things like this are why I've dropped from being a regular visitor doing 30-40 posts a day (I used to be ranked about #5 in total posts) down to about 3 posts a week. It's getting better, but a toolbar would make things much easier, and nicer.
