What are contact groups?

Contact groups let you organize your connections (or, for clubs, your members) into named lists. For example you might create "Weekend players" or "Mixed doubles" and add specific players. When you invite players to a tournament, you can select a group and everyone in it is added to the invite list in one click. Groups can have optional filters (e.g. level or gender) so that when used for invitations, only matching members are included. You manage groups under Account → Connections → Groups; club owners and admins have a Groups tab under their club's Members section.
