Site Update #2

We've added a captcha to help curtail the spambots from auto-registering. Took me 15 minutes to clear out three hours worth of fake registrations. It's currently enabled for the math formula submission which I think is easier for humans to do, but maybe harder for the spammers. We will see.

I've opened registration to real visitors with admin approval. At this time it is unlikely anyone will be registering as there is currently no content to speak of, but that will change.

spambots are more intelligent than I thought. I turned on the image captcha to see if that will help, had to clear out a whole new range of fake registrations.
