Okay we'll help you find your path to becoming a commenter. It's actually quite simple.
First, navigate to the bottom of a post where it will say "New User? Here's what to do." Click that link. Now you have to enter in your audition post; make sure it's good.
Next, pick a user name and password. And finally you can toss in your email address for password retrieval, if you're the forgetful type.
Like we said earlier, this is an audition. So after 24 hours, if your comment still isn't up, chances are you didn't cut the cheese (Get it rat/cheese? Never mind). But never fear—you can try again.
And as usual, you can check our Comment FAQ for any other commenty questions.
