It would be useful if there was a category (or subcategory) of scientific domain (e.g. physics, methematics, economics...)  in which Maple is applied. Thus it would become very convinient for someone who have a question on a specific topic to find a possible answer. 

I like how the Julia community has been organised in https://discourse.julialang.org, so I would suggest to implement something similar in Maple Primes
