To register, follow the link; you'll reach a page that looks like this:
In the top right corner, you can see two buttons, one marked "Join", and the other marked "Login" - click on Join.
You can choose to join using your Facebook login information, your Google account, or using your own email address to create a new profile.
If you choose to create an account based on your email address, you'll see a form like this. You should fill in all the fields and click "Sign up with Email" to
complete the process.
Fill in the information required and click to continue; on the second page you'll finish registration and pick a user name. The user name will be shown next to each message you post; it can be a 'real world' name or nickname, whichever you like. Once you've registered, you'll be given a profile page where you can fill in any information about yourself you like - or none, if you don't want to; though we'd encourage putting a bit of blurb about yourself so everyone knows who they're talking to. Remember your profile is public, though; don't put sensitive personal information, such as your address, there.
This will give you basic access to the forum and allow you to read and respond to discussions in the public area. If you are a paid-up club member and would
like access to the members-only sections, you need to send an email to the forum admin - there is a link in the forum index page.
