Understand that there is not "a mod team", W3DHub is a collection of W3D based projects (and quite possibly with more on the way), managed by their respective project leaders. For the creators, this is their hobby, they do this in their spare time for their own entertainment and at their own expenses (none of this is free). They are not here to work on projects they have no connection with, and forcing them to do so will get poor results, as there would be a lot less passion going into the work.
We all would love to see projects like AR release sooner rather than later, but we're limited by what individual people can work on. Take me for example, I am currently trying to find time for an AR level and documenting the process, but I am still very much limited by factors such as time and motivation, and these have to align for a hobby project.
