Random ... Which is a good way to start!

I think the strangest thing about setting up this new blog is that I don't remember signing up for this service, and apparently I did, sometime in my sordid past! I went to register, and it told me that "wendebular" as a log in name was already taken. Flustered, I tried it again (this has never happened to me before). Still unavailable. As far as I know, this is a unique name. So I figured I'd try and log in as wendebular anyway. My GMail password didn't work. However my Yahoo! password did! There were no profile details or anything, so I'm utterly confused.
