Systems and methods for notifying users of upcoming communication sessions in a virtual forum of an online community, for example, a video or audio forum, in which multiple users “hang out” and communicate. Users are notified of these upcoming meetings in advance, so they may participate in them, even at short notice, for example, in the event a meeting is ongoing. In some embodiments, the systems and methods permit users to subscribe to a particular entity within an online community, which may either be individuals (for example, a celebrity), company pages, groups, etc. Those who subscribe to the particular entity are immediately notified in the event a meeting relating to the entity is designated to occur or is ongoing.
