Are you YES or NO or perhaps still making your mind up? There will surely be a very high turnout when the polling stations open on referendum day. Are you registered to vote though?
The Electoral Commission website "About my vote" states:
"If you’re not registered, you won’t be able to vote. In October and November 2013, each household was sent two forms by their local electoral registration office requesting the details of all those who will be eligible to vote.
If you have not received your forms or need new forms, you should contact your local electoral registration office. You can get their details by entering your postcode on this website."
And that on line form is available here. You still have to print the form off and physically post it to the electoral registration office though.
