Begin by clicking the red [Sign Up] button in the upper right corner of every forum webpage.
The popup window gives you many options to sign up by either creating a new account using your email, or by using any 3rd party credentials you may already have, e.g., Twitter, Google, Facebook, or GitHub.
After you have signed up, a forum moderator will review to approve your request. You'll be notified by the email you have provided or that is linked to your 3rd party account.
Once approved, you can return to the forum and log in with your approved account.
