MATCH IT FOR PRATCHETT

Today, it was announced that Terry Pratchett has donated half a million pounds to Alzheimer's research. Hearing that, it occurred to me that if half a million of us all donated a pound to Alzheimer's research, we could match his donation and make it an even million.

So whaddaya say, guys? It's a pound. That's about 2 bucks US dollars, give or take a couple of (US) pennies. You can spare that much. Go here and make your donation. Tell them it's in honour of Terry Pratchett.

Let's do it!
