Most clubs meet at least once a month. Meeting more than once every two weeks may be a hassle. If your members feel like all they do is meet, it's time to lighten their load. Schedule and organize it as soon as possible. Events thrown together at the last minute may work, but it does little for club camraderie, teamwork and attitude.
Advertising is in many ways more important than the actual event.
The reputation, influence and success of your club depends largely on how well you advertise. There are usually several mediums by which you can get information from point A to the campus population. If you choose print medium, make certain to have your logo displayed in the advertisement. After a successful event or two on campus, membership tends to increase. Put these new people to work.
