Hi, Bob - Salvation Army's a great idea; I decided to donate to
http://www.redcross.org.ph/donate
which is the Red Cross organisation in the Philippines - obviously there's going to be a huge effort to get these folks fed and sheltered and I thought money going to a local aid organisation would let them do a little relief work immediately.
There are probably going to be many fundraisers in the UK as well to help get supplies quickly to the disaster area.
