I can help you meet tennis partners. As a member of Tennisopolis, you need to think about incoming requests as much as outgoing requests. You should upload a picture for your profile (could be of anything you like), plus you should list your level as accurately as possible. It is a fact that members with profile pictures get invited to more tennis matches.
Be sure to join the Group(s) in your area and introduce yourself in there in the local forum and the comments section too. Surf through the members of your local groups and leave nice comments on their pages and send friend requests.
If anyone needs help finding a partner, let me know and I will review your profile and search for some good partners.
Have fun out there!
