I advetised this site on another forum to see if we could get any new members I know of one person who registered but they havent got the validation email. Im not quite sure if theres some kind of problem but because of that they cant do anything

I'm afraid i'm not entirely sure how the validation email thing works. For the majority of people, I believe it works automatically, but i do try and check the list of those waiting to be validated as often as possible and click 'validate'.

It may be that your friend had a slight typing error in their email address when they signed up, meaning they won't recieve the email. In which case, I would suggest trying to sign up again.

Out of interest what username did they sign up with?
