It is indeed.
The charity has also been in touch with me as Chief Twit asking how they can help, so I've requested they retweet any promotional tweets and also pointed them towards the Facebook page for sharing status updates. For those not up to speed, it's here: http://www.facebook.com/YourDonationCounts
They also asked that I pass on their thanks to Trish for nominating them and I'm very happy to do that as publicly as possible.
