I have found DD to be very receptive to ideas and conversation. I would suggest contacting DD at firstname.lastname@example.org
and express your concerns in a polite, professional manner and they will consider the suggestion. If it doesn't work, they will explain why.
It is a good idea when pointing to an issue to also provide a solution. Suggest a solution directly with DD.
Personally, I was thrilled to have 2 women at Centennial. I was also thrilled to have a 10 yr old and father play. I didn't realize we had a 13 yr old kick some hiney as well. Cool.
