Each week we ask the readers of scotlandonsunday.com for their views on a burning issue from the past seven days. The best responses may be reproduced on the Online Forum page in Sunday’s print edition of the newspaper on October 23rd. If you wish to appear in Scotland on Sunday, then, along with your response, please leave a first name and surname, as well as your location - eg Tom Smith, Edinburgh. We welcome all comments. The question this week is... Should the news about the North Sea’s longer life as an oil producer alter the independence debate?
