Computer-based systems and methods provide additional management options for members of social networks whereby the members can define and participate in conferences, with the extent of the participation and messaging within such conferences based on the structure of the underlying social network(s). Metadata sent by participants includes one or more distribution parameters, with the parameter(s) specifying the extent to which a message is distributed within a conference and/or the extent of participation in the conference. In some embodiments, replies to messages cannot extend beyond the original recipient list, but may be further limited. Embodiments of a client interface for use in social networking conference systems are disclosed, and may include threaded chat areas and content sharing areas.
