Hey kiddos, it's easy to sign up to comment on our fabulous posts. All you have to do is fill out your witty, clever and spell-checked comment then select a username and password. Your comment won't appear at first because we have to approve you as a worthy commenter. Be nice, though. We regularly execute commenters.

Tip of the Day: Gina over at Lifehacker came up with a Greasemonkey script to let you reply to comments just by clicking on a link next to the name. Makes life a lot easier when you comment a bunch.

Check it out here.

Turns out that script isn't quite ready for Gizmodo yet. We're working on it though.
