This is one the most delayed items on my to-do list. I know for ages people have been forced to enter comments without a preview function. I had disabled it some time ago when some sort of bug prevented the comment preview window from opening. In any case, I hate popups, as do most people. Now there is a live preview function. When you type your opinions, your insights, and your insults into the comment box, it is simultaneously rendered exactly as it will appear to everyone who reads it. This includes any HTML you enter, so feel free to use boldface and italicized fonts, links with anchor text, lists, anything you want. If it's legal, it'll render, and you'll know what it's going to look like. Once you're satisfied that you've crafted the near comment, hit "Post". And thanks for joining in!
