New Security Measures

Okay, so we had some spam problems just before I went away. I seem to have curtailed them registering a new account by adding a security question. What is the number of residential lots in the original game?. If you're already registered you don't need to answer this. Also answering incorrectly should give you clues to the correct answer if you're having trouble.

Additionally, once a user does register they must post at least one comment somewhere or anywhere so I know they are human. After the first comment they will be approved to post without being moderated. If you are already approved this does not apply to you.
