New mods to help stop spam!

OK, I realized that the spambots were getting out of hand ... for one day, I switched the registration confirmation to be approved by me, and it was so overwhelming that I decided I needed to take action. So thanks to links from some of you, I've installed three mods:

1) There's a new question in the registration form, which I plan to change periodically to keep ahead of the spambots. Right now, the question is, "What is the background color of the Zen Habits blog?" I'm hoping the obvious answer is white, but if not, I'll find an easier question. This should prevent most spambots from getting through.

2) In addition, if the spambot tries to provide profile info during the registration process, they will be flagged as spam and prevented from registering.

3) I've blocked guests from viewing the memberlist as well as user profiles. This is designed to remove the incentive for human spammers to register ... they are trying to get the search engines like google to see the link to their site from the forum profile and memberlist, but now the search engines won't be able to access those pages.

Also, the regular capcha for phpBB is activated.

I also removed the subsilver theme (as sid noticed!) because I was installing a bunch of mods and it's too hard to do it for multiple themes ... so, for now, people are stuck with the default theme. Hope that's not too much of a problem.

Lastly, I will make an announcement in the announcements forum, but I've assigned ranks to different numbers of posts ... most people right now are "New Zen Habitants" :)

Let me know what you guys think of these changes, and if you have other suggestions/comments. I hope this will reduce the amount of spam by a dramatic amount. Also, I will be deleting the spam accounts that are there right now -- which is a little disappointing, as we had passed 300 members! :)
