Congrats on the (re)launch! I used ThinkVitamin a little bit earlier this year, and it's great to see you guys moving forward. It wasn't for me at the time, but may be in the future. I don't know if it was just the timing (I was really busy) or the format (video isn't for everyone), but I was impressed with the product regardless.
One thing to note on the new site: clicking "Sign your team up" on this page: http://teamtreehouse.com/groups just takes you back to this page: https://teamtreehouse.com/subscribe/plans, where clicking on "Sign up" takes you to a page with no indication of how to sign up for a group plan.
Thanks for pointing that out. We're working on a brand new Groups product that will come out in one month. It'll have a custom signup process.
For now, the way Groups sign up is like this: Sign up and then add "sub-users". It's not elegant, but it works for now. Then in a month, we'll launch something super sweet.
