Your work is very fascinating Randy. It has inspired me to take some programming & data/statistics classes (which I'm already enrolled in after finding these gems last month). Thank you so much for everything you have done with RSiteCatalyst. I swore I saw some kind of link for an Adobe Summit 2017 session you had or that you were associated with earlier this year. I'm kicking myself in the foot that I didn't get a chance to attend that session if you did in fact hold a session at the Summit.

Oh and you probably saw my linkedin notification because I couldn't find a way to send my gratitude when browsing your site. My name is Kalen Daniel, and I do web analytics and work with the implementations as well as create reports/visualizations (well dumb-versions compared to R at least! with excel/google sheets and scripts from clickstream data which has been painful to say the least). Just mentioning that because you may have seen when I was poking around to find out more about your work.
