You can use any and all HTML when leaving a comment. If you want to link somewhere, and as long as you're not spamming me I encourage you to do so, it's best to leave the link in proper tags rather than just dump the URL in. For example: <a href="http://www.somewhere.com">somewhere cool</a>.

Posts are automatically formatted for paragraphs so you dont need to use <p> or <br> tags

If in doubt just write stuff. I can clean it up later.
