The goal was to have a membership site with a bunch of training videos. An example of what was created can be seen here.
There are plenty of plugins that give this functionality but I custom coded most of the features needed to launch this.
Then it morphed into an idea involving email funnels.
I was studying some popular email marketers and decided to capture their funnels in my inbox and look for patterns.
I thought this would be useful for other marketers so I started publishing their funnels in a custom post type that I created. I hacked the built in WordPress category feature and here is the result.
If I ever find more time I will create more videos and find a way to automatically update the WordPress posts when new emails hit my inbox.
