Nope, didn't work.
I'm wondering if it has anything to do with the Auto-Tagger mod that I have installed.

This is strange. I'm just starting my site, so I had a few test posts and the test tags were in the side column tag cloud that I added. So, I went to the tags piece of the admincp and tried to remove them. That's when I reported my issues a couple of posts ago.
But, now I moved those test posts into an admin-only area (to avoid deleting posts/threads altogether) and I added a few new threads/posts and the 'test posts' are gone. Sheesh.
As long as things are good, I'm good. But, very strange that it would 'fix itself'.
