Bleah!  My website broke for a bit there!  At first, I thought it was possibly due to a hack, but then everything I looked at was fine.  It wasn't related to an upgrade to my browser or my server's php version.

It looks like I was using $_SERVER['SCRIPT_URL'] which appears to only be available in unusual circumstances.  The better alternative is to use $_SERVER['SCRIPT_NAME'].

There are few more things I want to improve upon for the memo blog/mini-review.  I want to add comments.  This is more important now with the addition of the mini-blog, which I admit I have not produced anything yet.  I want to add the ability to hide certain posts.  I also want to be able to manage what tags are hidden using the admin page.
