Further to my last petition update here
http://doctorwho.livejournal.com/7843140.html#cutid1 there is more good news.
A few hours ago the wonderful people at Davidtennant.com reposted the petition link on their facebook site. I am pleased to say that as a result of that we've well and truly broken the 10000 mark. As of a few moments ago we had 11116 signatures. We'll have to do our usual sweep for duplicate names but this is just wonderful.
