The JetBrains TV site now hosts two new introductory screen-casts loaded with practical tips and tricks that aim to help people start using MPS effectively. While the first demo describes how to work with the MPS editor, the second one illustrates ways to run your solutions either from within MPS or integrated into a Java solution. If you are an MPS freshman and want to get useful tips, check them out.
Develop with pleasure!
