Ladders are great events to have to get players engaged without specific time constraints on playing matches. ManageMyMatch provides standard Ladder systems to be set up for either squash or tennis using the Nextgen Event feature.
Simply go to New Nextgen Event, select your club, sport and the Ladder event and hit confirm. You'll also be given the opportunity to request a banner advertising the event with a quick link for members to press to enter.
Members will then be able to enter the ladder in My events and start arranging their games. You won't even have to preset a new comers position in the ladder - ManageMyMatch has rules (see this article) to ensure members can challenge (invite) others appropriately to get started.
The standard rule is that players will be able to challenge others above them in the ladder but no more than the next three players. This can be adjusted in Manage Series to any other number if you wish. You'll also be able to adjust/review the match scoring rules and any other details (like eligibility).
If you wish to make adjustments to the rankings, click the Manage Draws and Joiners link which is shown when you select the ladder in Review Nextgen Events.
