As a leader,I like to find my own challenges as I know who I want to give games to.
So supposing I want to find a game for a player of average rating 1500:-
First I have to filter for clans accepting challenges.
Then I filter by recent challenges as there's some clans with unresponded challenges from months ago.
I then have to go to each potential clan and see if there's an available player matching my requirements.
An extra filter - "clan members available for challenges of average rating......" would save me a lot of time.
I would also like to "amend" an issued challenge on occasions without having to withdraw it and re submit as if a challenge is rejected, I may like to include one or more of the "rejected" players in another issued challenge.
