Second Vice President

The Second Vice President is one of the "working" positions. In the terse words of the Bylaws,

The Second Vice-President shall be in charge of organizing 
fellowship activities.

Ultimately, this means that the 2nd VP does the most work out of any of the officers. It is the 2nd VP's job to plan, organize, and effectuate all of the organization's events. Whose job it is to notify the membership of the events is a topic that has been debated vigorously in the past. While it seems that it would more properly fall to the Corresponding Secretary to notify the membership, it is often more efficient for the 2nd VP to do so.
