I decided to get rid of the Guestbook and Newsletter for now.  As you've no doubt guessed, I'm still working through all of the ideas I have for the site, so things come and go as I toy around with new ideas.  Given my tendency to love change, it may always be that way, but I would expect things to calm down in the next few months as I become more comfortable with the overall functionality of the site and how I want to use it.  Until then, though, expect things to come and go as I play with what works and what doesn't.
