It's a good idea. I think we could create a separate forum like a Yoga encyclopedia where people can start threads on popular Sanskrit terms used on the forum like purusha, prakriti, vritti, karma, dharma, samkhya etc, and various members can contribute to it by adding to the definitions or giving alternative definitions and discuss and debate on the matter. It would be very helpful to the Yoga forum readers in learning Sanskrit terms and becoming familiar with the underpinning philosophy.
I do think what most Yoga forum members are lacking is a grounding in its philosophy and an understanding of core concepts like say prakriti. This is in my opinion more important than the practice itself. Such an encylopedia could make the Yoga forum one of the best resources on Yoga on the web.
Each Sanskrit term is LOADED. You can hold an entire discourse over just one word. The word Yoga itself is full of meaning.
