So, it seems you were curious enough to make it to this page or you had too much spare time on your hands. Congratulations! LOL
Now, here's the explanation for the existence of 2 guestbooks. The one you just saw was the first one this site had and it was managed by Geocities. When Yahoo took over Geocities, that type of guestbook stopped existing and Yahoo introduced its message boards, which I didn't like too much. I wasn't the only one who didn't like that Yahoo terminated the Geocities style guestbook; consequently, Yahoo received what they call suggestions (I call them complaints) about putting back up the old style guestbook and that's what they did.
Because I like the old style guestbook better, I put it up again on my site (now that Yahoo supports it).
So, there you have it. Feeling more knowledgeable? :)
