Treehouse REQUEST: Practice problems

This is a question (or more of a request) to the staff at Treehouse. I love this site. You all have done a FANTASTIC job. I've tried a few different online courses and I think Treehouse is by far the best option to choose from. I recommend it to everyone who has even a slight interest in coding or learning to code.

All that said, I think there's one area that could be improved upon and that's practice problems. I think it would be great if you had an area for members to practice their skill on various programming problems. I'm also a member of CoderByte and they have an excellent practice problem section and even an area that gives you an idea of common interview questions, which is also very helpful.

I can't say that Treehouse really needs it to be ahead of the curve, but I think it would solidify your position for years to come, as this feature would be of tremendous help to your members.

Just a thought.
