We have been getting a number of automated spam registrations of late. To prevent this, all would-be registrants are now required to do some simple maths  during the registration process, and all new registrations will need to be admin approved. You will also be required to fill in a more detailed profile, prior to approval.

No big deal, just that there will be a slight delay until admin actually approves your registration, or rejects it if you are an ugly, horrible six-legged Internet bot on a mission to spam the world. 

Using your "proper" e-mail address rather than a spammer-favourite Hotmail, Gmail, Yahoo or similar account, will also help.
