We have a very unique way for using the resource manager as a site sharing educational resources: http://tag.ac/teaching-resources/
It's been set up to use a wordpress interface before taking you to the resource manager area.
We've also made a guide for users to upload resources http://tag.ac/tutorial/how-to-submit-a-resource/
Please feel free to refer your members to our guide for help, or make a derivative (with attribution for the source)
We're in the top 2 million sites (200,000 in india) but currently have low activity.
