Go, try to break!
There is one teeny error I'm still tracking down that gives you a header error when you log out, but otherwise, registration should work, and logging in and out. When you're logged in, it should say hi. It should give you various standard errors when you forget vital information, and shouldn't let you register with the same first and last name (a spammer technique). I can delete any test accounts you don't want to keep later.
If you already have a registration at Portrait Adoption (a customer registration, not an artist account), just try logging in with that. Or create a test account. Or whatever you like.
Thanks in advance! Lemme know if you find any errors.
