If you take the "remove from list" option, you should only remove if they're going to have him as their no1 pick.
Hi, yes that is the idea, so when someone ask for a rider, they must tell me if it will be their top pick or not.
We can do an Australian database, I will contribute whatever way you choose to do it 
Thanks for the enthusiasme

but I am too lazy to manage/admin an online excel google doc.
But it is a good idea, google docs also gets blocked from work

I also want to prevent "competition" for the same rider when everybody see how good his info is.
