Just wanted to share two tips about the forums. Feel free to add to this if you'd like a forum feature or if you've discovered a tip yourself.
You may have noticed (depending on your contrast) that when browsing any list of topics or threads that the entire row is clickable, not just the link itself. I find this personally very useful as you have a much larger "target" to hit when clicking around.
When posting there is an access key associated with the post button, so for example on Mozilla I can hit ALT + P and it will post the message. I'm not sure exactly what the key sequence is on other browsers such as Safari, IE, and Opera, but it's something + P. If you know please share.
