Some tweaks to the website

I've made a few changes to the way the site works, the most important of which is disabling anonymous comments. It appeared that in some reviews and comments people were not being honest about who they were and what relationship they had with the gyms they were reviewing, so people are now required to register. People without accounts can still rate gyms, but can't leave reviews.

If you have any thoughts or suggestions, please post a comment here, or send me a message via the contact page.
