Hi. I took a look at your event. Usually, "events" on this site are things with specific dates. I noticed yours looks like it is running every day until 4/2012. Maybe you can change the event date in this case to the sign-up deadline... Also you named the event Angelika, so I edited that. Take a look. You can also search around the site for players and Groups in your area and let them know about the league.
Welcome to Tennisopolis, Angelika! To look for new partners, begin with the Meetup tab at the top of the page. If your area is not represented already, you can create a group using "+Add Group". Be sure to look through our forums as well.
