Not that I'm wanting to stir up a hornet's nest but when you 'follow' 'OakwellOfficial' on Twitter it links you to Barnsley One . Not an active profile yet though - ie no tweets or whatever they're called.
Where's it been said.... ....that it's the 'official' Twitter page? Anyone can make a twitter account up. There's a BFC page on facebook and then Stokes' 'Toby Tyke' ID as well. I don't think that's run by him.
RE: Where's it been said.... It hasn't. But someone like Mark Stokes knows better than to call something official when it isn't.
