We just received an update from Kurento media server that in the latest nightly build the issue with broadcasts is solved, so we are currently updating the media server on our dev servers and as soon as we can confirm that the issue with library is solved we are going to upgrade the platform as well. After that, Kurento should work properly and no other issues have to occur.
When you going to launch platform in full mode? Are you going to hire models? I think you must increase marketing, as may be just a few viewers and only few models know about this platform.
