I think it's better to know who among you are playing tennis and who are interested to learn tennis before setting up an eb and I believe that a club can be a good start. I've noticed that having a tennis club is like a family while playing tennis. It is also one of the best way to learn tennis because you will know what class(skill) do you belong and help you to improve.
A tennis court without a club is useless and an eb without a club is hopeless (I think). So who wants to join?
