'Singing sections' do not make sense as they are a mockery of the whole aspect of support.
A large crowd is going to be noisy and adding tribalism, a fair serving of intoxication should automatically make it clear you are not going to be sitting in a library.
Having designated areas all to easily leads to 'excuse me if you want to sing then go over there, this is the non singing section.'. Can see stewards asking to check your season tickets for a note stating 'this person is allowed to make noise'
As for moving the family section to the RDS? Smacks of someone in the marketing department spotting its the only stand with facilities to host extra curricular items such as face painting etc. They want to create an unrivalled atmosphere and yet they want to remove a section of the ground which helps generate what little noise comes out of the dons fans.
Move the family section to the Main Stand and hand over the ENTIRE Merkland to the general population. Its low roof is similar to The Shed at Tannadice so the potential for creating noise is clear.
