Me too. In 15 years of Web Development I've only had to build my own regex a few times, and most times I use other people's from stack overflow or elsewhere. This is a great intro to how to really use and build them and I would highly recommend to anyone else.
Fantastic series explaining RegEx in small, manageable chunks. Liked how the series was applicative in nature and reviewed what had been explained in earlier videos when building more complex patterns later on.
