User Registration Changes

[insitu_az]

Hi....
Since our old site domain has now expired, I have made some changes to the user registration:

1. I went to a clearer anti-spam image. I think the default image was very difficult to read, and probably causing issues with people signing up.
2. I went from an automatic verification to a return email system for new sign ups. It will now require you to return an email prior to being verified. I think this is the system we had on the old site.

I don't recall the old site having many issues with spammers, using similar controls, so I think this should be sufficient to maintain security for our forums. If you have questions or concerns please let me know.
