Echo, echo, is there anyone out there...?
It seems that you have succeeded in shutting down activity in the community by relegating the links to the GrabCAD community to an obscure position, hidden away on a webpage that deals with the subject: 'Making Additive Manufacturing at Scale Possible'; a subject that clearly interests very few of your (allegedly) 7 billion+ members. So, are you satisfied? Is this what you wanted?
If you can't handle the bandwidth demands from an active community, then let us know rather than tweak your site to something that is totally remote from the expectations implicated in your wonderful site name: GrabCAD. The place where you grab (=find and download) CAD models, not high-end software for 3d printing companies.
You are forcing everyone that cares about the community onto new pastures and that is a very sad evolution in my opinion :-(
