Hi,
The BBC have been in contact with us at Wikimedia UK about the possibility of them getting access to some Wikimania footage. I quote:
"We are expecting to film with Jimmy Wales later in the year, but we were really hoping to film at Wikimania. Unfortunately, due to schedules, we simply can't get a crew to the event. And so, it occurred to us that, rather than lose this quintessentially Wikipedian moment, we could - in the spirit of our shared open and collaborative goals - ask some of the attending Wikipedians to shoot some footage for us, for release on an open platform (Kultura) to allow all parties to use the footage under creative commons."
They ask interested parties to get in contact either via their web form here: http://www.bbc.co.uk/digitalrevolution/contactus.shtml or via me/other WMUK board members. (E-mail me and I'll forward it on to them, or alternatively, if you're in the UK email me and I can give you the organiser's phone number.)
Thanks,
Tom
