I looked through the content, so can vouch for this course. I use this theme for my membership site, which I can integrate with my email software, Ontraport. Connection comes from real human interaction.
When you have your site custom designed like ours, you can hard code a lot of these plugins, which means your site will run faster. To me, the crux of all online endeavors is good writing. Who are you serving and how can you help them? A premium theme is an investment into your business.
