To prevent hideous amount of spam, you have to register with Fametastic to be able to post on these forums. It's really easy to do though.
- Click on the Register link near the login boxes on the top left
- Fill in your desired username and your email address
- A password will then be emailed out to you
- Then just login with your username and the password
You can really easily change your password for future use by clicking on your profile page (once you've logged in, there is a link to it in the "Login" area at the top left).
Your login covers both the forums and the main news site so if you log in here, it'll remember your login when you post comments over there too :)
