Allowing a higher ranked player to challenge

Hello,

I was wondering whether you could allow a higher ranked player to challenge a lower ranked player.

You might ask: why would you need such thing?
The answer is: I am currently running a league and often players forget to challenge before playing. The problem when this happens is that the higher ranked player can't record the game score. Only the lower ranked person can challenge and report the score.

Could you implement this feature? It would also be easy for me to justify why my college should donate to squash ladder site.

Cheers, Lee
