• New theme Something not white-on-black Maintain the original logo, perhaps? Maybe dig out the old cartoon face one?
• Implement the links on the left navbar so they actually do something other than error
• Add post/comment voting support
• Implement an RSS feed ** Add ability to skip publishing blog posts to the feed
• Implement the ability to set the blog post type and status when posting
• Add support for editing a blog post
• Add support for changing a comment's status
• Add user management * This will be especially useful for all those `guest-` users ** Add support for promoting a guest user to a standard user
• Add audit logging ** Track source IP, date/time, action
• Improve authentication headers ** Right now, the sessions time out way too quickly, which would be VERY ANNOYING if writing a long post *** Maybe do something with that so that it saves the post and allows you to log in, then it submits the post again?

That's all I can think of at the moment. Here's hoping the markdown list works...
