To make your member administration even more insightful and clearer you can divide your members in groups. Think of for example Boards, Commissions, year clubs, etc.
How to use a group
Groups are divided into folders and possibly sub-folders. In the example below the root-folder 'Commissions' is divided into five sub-folders. The sub-folder 'Conference' contains the conference-commission of 2013 till 2015. This way you can keep an overview of the yearly changing commissions and its members.
