What is GFDatabase?
It’s a WordPress theme that allows you to store questions (along with hints and answers) on various topics. The theme takes care of the tough stuff: choosing questions randomly for display on the Question Feeder page, hiding the hints and answers from view until the visiting party summons them, sorting and displaying questions by topic, etc. It also includes the standard blog posts/static pages you would expect in any WordPress theme.
Because I’m a nerd. The original purpose of this website was to feed myself random questions on Geophysical Fluid Dynamics (GFD) as a study resource. I guess it could also stand for “Giant Friendly Dolphins” or “Gluten-Free Donuts”. As long as you remember it, I’m happy!
