Your 1st challenge can be for any position in the ladder.
After that, all challenges must be within the Challenge Range.
(Ex: You are #7. The Challenge Range is 3. You can challenge up to #4)
If you are unable to find a match in the Challenge Range, you can challenge up to double the range to find a match.
The player in the higher position has final say on court location and suface if an agreement can't easily be made - a benefit of signing up early :-).
The challenger provides the balls.
Matches can be played at any location.
Etiquette Note: If Player A wants to play a match at a location where they are a member and Player B would have to pay, Player B should be told ahead of time. It is suggested that the court cost be split.
If you you have any questions/problems, let us know.
