Abstract: A system which hosts an electronic forum comprises memory in which is stored profiles of users of the electronic forum, memory in which is stored posts of the electronic forum, and notification generation circuitry. The notification generation circuitry is operable to, automatically in response to creation of a post to the electronic forum, inspect the post for an occurrence of a particular tag. The notification generation circuit is operable to determine, automatically in response to a detection that the post contains an occurrence of the particular tag, which of the users are both subscribed to the particular tag and have permission to view the post; and send, automatically in response to a determination that a first one or more of the users are both subscribed to the particular tag and have permission to view the post, a notification of the post to the first one or more of the users.
