I was excited to take up this opportunity and just signed up last week. So far, I have taken a few classes and I am quite impressed. It's flexible, detailed and fun.
The only problem I am currently having is that I accidentally clicked on the one-click purchase and sadly, ended up paying for something that I do not even need as I was just exploring the site. I emailed couple of times and still have not heard back from anyone in this regards. It will be great to have more improved customer service and hopefully I get a refund and if making a purchase, will pay for something that I need.
