I’m good at speaking in non-technical terms. I recently met someone just as good. WordPress Building Blocks is a web company operated by Susanna Perkins, whose customer service skills amazed even me (I’ve written whole books on the topic. I’m fussy. Way fussy.)
Susanna uses WordPress for her clients’ sites. She has a 7-installment newsletter that walks through the concepts behind your website at the most fundamental level.
If you’ve ever struggled to grasp what hosting and domain names and stuff like that mean to your WordPress site, sign up for Susanna’s short series. It’s super.
