On occasion when helping someone with their homework or other problem, I have come up with somewhat different problems that I think would either be useful to people trying to learn the stuff or just fun to others. But I don't see where an appropriate place to post such questions would be.
So what I am proposing is a forum dedicated to problems posted by members as friendly challenges to other members. The spirit of the forum should be such that the expectation is that the poster has already solved the problem and is expected to either post the solution along with the problem or to specify a date on which they intend to post the solution. People that suspect that it is a ploy to get someone to do their homework can either say so or can just wait until after the OP's solution is posted before contributing.
I envision a variety of threads, ranging from very simple problems that have some little trick or sutble element to very challenging problems from experienced members aimed at other very experienced members in which the OP answers lots of questions and gives out hints over time before revealing their solution.
