Thanks guys, I do appreciate it!
While support isn't in a position to create Wiki articles lengthy enough to warrant chapters (verging on courseware) I can see the possibility of creating individual articles that over time help cover a specific topic. We also don't want to duplicate the information already available in the Help file unless there's some specific aspect that's missing...?
In the interim, that first eatyourcad article by Nigel seems like a good one, and nicely covers the creation of a new Catalog Type.
