The Lodge was created by me, Chris Coyier, one of the founders of CodePen. It's the membership-based learning section of CSS-Tricks. While it is commonly used as a learning resource, it is also sometimes used as a teaching resource. Using the videos in class is allowed and encouraged.
Because of that cross-over in interests, we though we would do a cross-over promotion as well. If you're Super PRO here on CodePen, you can have a complimentary Bear-level account on The Lodge.
If you have a Super PRO account, just shoot us a support request about it and I'll get you all set up on CSS-Tricks.com.
