User Signup Change for Website

I was looking through the user list and noticed quite a few users that were created by bots. They had names like: ErxeSt_3UsdWqnuare and such. I had the sign up pretty loose in that there wasn't any authorization to create an account.

I've had to change this. For any new accounts, they will have to be authorized before getting access. If there are any messages with spam, please let me know and I'll remove them.

Sorry for any hassles.
