I sincerely recommend that you continue on the live site, and when you can, and are comfortable, please help us in the QA effort as well.
The more people who join in this voluntary effort, the closer we get to shipping them to live website.
Again this completely by choice, and we need help in covering QA for all of the challenges, thoroughly. So jump in if you want to be this first to find out a bug, and help in getting it resolved. We value your contribution a lot.
Thanks and happy coding!
