Okay, so I tried a couple different ways to make this log look like the rest of the site. In the end this is what I came up with. Tasha, my wife, is the one who pointed out that I could simply have the forum, guestbook, and log all open in separate windows. Why I didn't think of that I don't know. Maybe it's fatigue.
Anyway, this is all up now and though I'm still not happy with the guestbook or the forum, I think this part of the site will be alright. That's all for now.
