I disabled blog entries for Registered Users since it was drawing a lot of spammers for some reason. Even with moderation, it was adding a bunch of extra work to clean up the spammers. I've added a new user group called Bloggers that I will gladly add people to if they want to write or manage their own blogs. If you already had a blog, I've already added you to the new group and you should be able to continue blogging away. I'm sorry for the inconvenience. Spammers suck.
