Not into Twitter yet - apparently I have an entry on Facebook and sometimes I can actually open it!
E-mail is a thing of wonder to me! The only problem is that so many other people know how to use it and they all seem to send me messages.
Our slightly more famous (and obviously more healthy ... and crazy) compatriot, Eddie Izzard, is on Twitter (http://twitter.com/eddieizzard) and is currently running marathons all around the UK for charity ... he can be sponsored at http://www.comicrelief.com/donate/eddie.
He deserves lots of support!
