1. A method comprising: determining, via a collaboration server, comprising one or more processors executing programmatic instructions stored in a memory, a response to a posting on a communication forum, wherein the communication forum provides a Web site through which a set of forum participants are able to view posts and the Web site provides responses to posts that have been submitted to the communication forum; and determining, via the collaboration server, whether or not to convey an email notification of the response to the posting to a posting user via email based upon a distance threshold established for email notifications, wherein the distance threshold is an integer value, wherein the determining of whether or not to convey an email notification comprises: computing, via the collaboration server, an average distance between historically submitted posts from the posting user and a quantity of responses from others before the posting user submits a new related post to the communication forum; setting, via the collaboration server, the average distance as the distance threshold; calculating, via the collaboration server, a current distance between the response and the posting, wherein the current distance represents a quantity of responses to the posting from forum participants that have occurred without a new response from the posting user being submitted to the communication forum; and responsive to the current distance being less than the distance threshold, conveying, via the collaboration server, an email to an email account of the posting user informing the posting user of the response, wherein if the current distance is greater than or equal to the distance threshold, the collaboration server does not convey an email to the email account of the posting user.
