Arden was an original hand on the former Grand Master's Hand to Hand revamp. He had started work on that project and was a major contributor to a document that summed up all the work previous--a document that was 31,000 words and roughly 60 pages of content.
Arden was diligent in proofreading and fact-checking. He was engaged and involved in every discussion, offered insight from various angles, and helped ensure that the final product had as much tweaking from alternative points of view as possible. He was a big factor in coming up with new Canon-friendly names for the new forms, and overall was a big creative boon to the project as a whole.
You can view the labors of Arden's work here on the new Martial Arts Forms page.
Thank you for your work, Arden. The ACC Staff appreciates the assistance.
