From an early stage in the proceedings, the SNP signalled that it favoured allowing 16 and 17-year-olds to vote in the referendum.

The issue was contentious - the SNP, Labour and the Liberal Democrats supported the move while the Conservatives opposed it - and finding a way to make it work in practice wasn't straightforward.

But in August 2013 the Bill that gives those born on or before 18 September 1998 the right to vote received Royal Assent.

From October 1, teenagers who will be 16 or older on the day of the referendum were able to register for their vote. Over the coming months, Electoral Commission canvassers will be giving out young voter registration forms to allow details of those eligible to vote to be collected. The registration forms can also be found online here.

The Commission has launched an advertising campaign on radio and social media, and has been working with education authorities and schools to ensure all those eligible get registered.

Children of armed forced personnel living abroad with their parents will also get an opportunity to vote, after MSPs voted to amend the law.

Under the Franchise Bill currently going through the Scottish Parliament, no mechanism existed to allow such 16 and 17-year-olds to have their say in the referendum. The amendment will allow for those young people affected to register to vote, so long as they can provide an address in Scotland where they would resident if it weren't for the fact that their parent serves abroad in the armed forces.

Andy O'Neill, head of the Electoral Commission's Scotland Office, said: "If you want to have your say at the referendum, you will need to be on the electoral register.

"We're supporting the work registration officers are doing locally by launching a campaign to raise awareness that anyone who will be 16 on 18 September 2014 can register to vote.

"Teachers can play an important part in helping raise awareness and we'd encourage anyone else that works with young people to help spread the message by using the resources we're making available."
