The most successful clubs have an outline and plan of what they will do each month at their meetings.
If you put together a 12 month plan for meeting dates and educational topics now, your members can add them to their calendars and you won't be scrambling at the last minute each month to figure out when you're going to meet and what you're going to cover at your club meetings.
StockRover has put together a nice set of 12 educational topics that you can use each month to learn something more about investing. Each one comes with some basic exercises you can do at your club meeting to help you try out what you are learning about.
