Thommo,
We employ two anti-spam/anti-bot measures that sometimes catch real people out. (It caught me out)
The first is the captcha. It says
DO NOT ENTER THE FIRST FOUR CHARACTERS
So it will look like BEER26fa
It is no co-incidence that the first four characters always spell BEER. In this example therefore you would enter 26fa
...
The second measure is the verification email. This always gets sent out. If you think you didn't receive it it's in your spam folder. If it's not in your spam folder it's because you possibly gave the wrong email address or your email provider employs an overly enthusiastic spam filter.
If you still can't register use the Contact Us form on the main page.
Let me know if you still have a problem
Will
