I have some ideas for apps to add to this website, so please visit every now and then.
If you have an idea for an app that you think would be useful, would benefit a student, or would make the world a better place, please share ( firstname.lastname@example.org ), and if it isn't too involved, and I have the time, I'll code the problem and make it a special app.
