My secret's out. OK. It wasn't really much of a secret, since it was posted on my blog, but my most loyal reader has spotted it, so I thought I'd point it out to those of you who haven't noticed.
I added a tab to my blog called "Cracking the Code," and it contains a guide to the nicknames I use most often. So, if you tend to have trouble figuring out who I'm talking about in my posts, you might want to bookmark this page.
