Need some details on Razuna to evaluate it for our requirements

Dear Razuna Team,

Can you please provide us below details to evaluate Razuna for our requirements.

  1. Do we have workflow capabilities in Razuna? Like when some one uploads an asset then we shall be able to approve it before making it available to view and download by other users. Like the feature we have in Resourcespace where we have 2 step - Pending Submission, Pending Review. Content in “Active” state will have to be configured as ready for consumption and download. Please let us know how can we do this in Razuna.
  2. Can you please provide some more details on the pricing for UNLIMITED Storage UNLIMITED Traffic plan shown at https://razuna.com/signup ? Is $149/month and only $0.95 per GB/month is a necessary expense even for a stand alone server?
  3. Can we deploy Razuna on our own instance of AWS without any additional support $ cost to us?
  4. Size limit of individual files that can be uploaded?\
  5. Number of concurrent users (searchers and users of material, not editors) supported on web-based platform?
  6. How is the Social Media Integration in Razuna? Can we post assets to facebook, twitter, youtube etc directly from Razuna?

Thanks,
Sanjeev
