Ask HN: Review our weekend project, quizforge.com

Given the post on the front page about selling to teachers (http://news.ycombinator.com/item?id=3011981), I thought it would be a good time to post a weekend project created by myself and someone else who doesn't frequent HN so much.

The concept is simple -- we're looking to make teacher's lives easier by providing a service that quickly/easily creates randomly generated quizzes on demand and ready to print. Only works for basic math right now, but we want to expand it into more complex math and different subjects. We have a long list of things we want to do, but its new and just now polished enough to show people.

We have some teacher test subjects, but we'd love to hear feedback from anyone. There are a few things we still need to add in and wire up, but the MVP is about 90-95% done and we're looking for feedback to iterate on.

Its our intent to have a freemium model where the paid account runs something in the $20/year range.

Thoughts? Suggestions? Good idea? Good price?

p.s.: as a warning, we'll probably wipe the user table within the next week or so. If anyone provides feedback and wants a free permanent account, drop me a line. I don't imagine HN will be the actual target user base, so I don't anticipate most people minding.
