Constantly logs me out and loses my progress
When it works, it's pretty decent, even the free version. The problem is that it doesn't ! It constantly logs me out, regardless of which browser I'm using (cache cleared, etc). I can be typing on the last question of a section and it pops up with the "You haven't logged in for a while." Sometimes barely an hour has passed! It doesn't save your progress, either, so clicking 'log in' will lose everything you've done up until then in that section - notes, working, thinking, answers, etc. It's incredibly frustrating and I've reported it a few times via the "Does this keep happening?" button, but I haven't heard anything back. I'm sorry, but it should save a state with your progress at the very least, so that when you log in again, you can carry on from the question you were on. For it not to do that is just poor programming / software design.
