I think it would be great to add a way for people to Subscribe to other people in the community so they can see when they upload media. Kind of like a regular activity stream except it only shows media of people you are subscribed to. This would be in edition to my previous feature request. http://rtcamp.com/groups/rtmedia/forum/topic/searching-sorting-and-tags/
@painx6 - Not sure regarding this feature as this depends on the number of people wanting this feature. Also if implemented this would most probably be part of rtMedia Pro.
