seems like you've been having some fun with the site.

More than I'd like to admit :)
I still am not 100% satisfied with the site. I would rather find a much simpler and cleaner look for it, but can't find a pre-canned Mambo template that does the trick. Perhaps one day I'll expand my limited HTML/CSS knowledge and design one myself.

I've been thinking of a series of mini-articles that focus on FAQs that I see posted over and over again.

That would be perfect!

could you give a few more specifics regarding your comparison of Mambo and Drupal?

Mambo tries to be everything, which is good and bad. It's good because it makes it easy for you to access almost every aspect of the site using a menu-driven interface. It's bad because it just feels too bulky. Very often easy things, that need to be accessed regularly, are buried under a couple of layers of menu-clicks. And comparing it with Drupal, it's slower too.
Drupal on the other hand is more minimal. You shouldn't really need to edit files manually, but there are less options than in Mambo, and they're more easily accessible.

In summary, comparing Mambo and Drupal is kind of like comparing KDE and Gnome, respectively :)
