Yes! I remember the thing!
I changed up the splash page last night to be a bit more interesting, and in doing so, I realized that I'd actually released the name of the site. Releasing the name obviously releases the domain name, and I didn't have any protection against people signing up!
So I added a simple security check to see if the site was offline or not, and whether or not you were an admin to login. I also added an option to turn off registration.
Now all I have to do is add those to the administration panel so I don't have to keep going into phpMyAdmin to change them. I'm trying to keep everything pretty changeable with minimal effort (such as the name of the points, page titles, things like that) simply because I change my mind so often!
Later tonight I'm going to continue working on the administration panel, get the bank done (at least partially - I'll be working with percentages. Scary stuff. But I want to do it now while I have the setup in my head) and possibly set up a simple game.
To wrap up, here are the newest started/nearly finished parts:
