I added a list of recent customers of ours here.

I also created a page for the course I am teaching: Introductory algebraic topology. The outline is there already and some of the articles have been written. The second one is Homology as a equivalence relation. Consider the question, What is a tunnel? It’s not as simple as it seems. It takes some work to find a good answer, the main part of which is: A tunnel is an equivalence class of closed surves.

Over the following months (it’s a two semester course) I’ll keep adding material as the course progresses.

I am also teaching Advanced calculus and some of this stuff will also find its way into the wiki.
