Abstract: A video capturing a user facing a camera is received. An image of the video is analyzed to identify a marking object in the image. The image captures the marking object held by the user in between the user and the camera. A gesture performed by the user is detected using the marking object in a space between the user and the camera. A location associated with the marking object is marked including by overlaying a highlight of a portion of content virtually shared between the user and one or more other remote participants. The overlaid highlight of the portion of the content is provided to one or more other remote participants via a collaboration medium.

Abstract: A system implements user permissions and user subscriptions with regard to content posted on one or more peer-to-peer knowledge sharing platforms (e.g., Community pages). Permissions are assigned to groups of users, rather than individual users. Permissions are determined by the groups of which the user in question is a member.
