WordPress 2.0.6 was just released, and you should upgrade because it has security fixes. It took me about 5 minutes to do the upgrade, and in that five minutes I received 4 spam comments because I disabled Akismet and WordVerify for the upgrade. Without those two plugins, I would be be absolutely LOST in comment spam. Before WordVerify existed, I had hacked in my own code which did the same thing, but without all the plug-in goodness.
*UPDATE* Be sure to also fix the rss issue.
*UPDATE* 2.0.7 came out. It's a security fix.
