>Primary Breed: the First Option should be Unknown -> see the drop-down list for breeds
Done

>Secondary Breed: the First option should be --- -> if this is selected then no secondary breed should appear on the horse listing
Done

>We should also add a list of all the breeds: "Other Registrations": that people can then move from the right column to the left column. If the move 3 breeds to the left column, then they have to upload 3 breed registrations or approvals (so 3 photos). This should also appear on the horse listing under Secondary Breed. This is an important aspect in the search engine, because great horses will be registered to 3-5 breed organizations
I'm sorry, but I don't quite get what you're saying. Could you elaborate a bit?
