In forums about photoshop, i can upload Images.
In forums about 3d rendering, i can upload project files
In forums about game development, why cant I upload my entire game, to run it in the browser?
Maybe limited in size and resolution, but that would be a kickass feature for this forum.
Its probably better to suggest something like that on the JGO website:
