This is the place where I blog https://andynashers.wordpress.com/
And my most popular post is on the Stanley VCP which I originally posted in January 2016 https://andynashers.wordpress.com/2016/01/14/is-this-the-cheepest-vcp-course-available/
They now have a VCP 6 install and config course and an optimise and scale course which I hope to take in the
future and will update my blog.
