Just getting back, I haven't commented on tsunami relief.  For myself, I find myself moved to give to various organizations.

I spent time in Madras in the early 90's, and particularly spent some time on the coast there, and made acquaintances there, so I am pulled to contribute in that direction. 

As an aside, one of the things I looked at when I was in Washington DC, were the various War Memorials.  While at the Vietnam Memorial, I simply couldn't get my head around the fact that twice as many people died in the that 4 hour window of the tsunami, then the number of americans that died in the Vietnam War.  The loss is truly unfathomable. 

At any rate, here is a link for organizations to donate to:

If I am missing some invaluable links, please let me know, and I will add them asap.
