If you need to contact me, there are a few ways to do it. For many inquiries, email will work. My email is firstname.lastname@example.org .
If you want help from a more public form (recommended) you can ping me on the Mathematica StackExchange chat .
Finally, I'm trying out including comments on pages, so there is a comment area at the bottom of this page. I'll see all the posted comments (and helpfully so will everyone else). If this works well I might expand this to some other pages and posts.
