Glad to have you back, MF, and you are too kind to Lagos! (BA recently started flying in there again, didn't they? - earlier this year a colleague of mine who had never set foot on African soil before had to fly in to Ghana & make his own way to Lagos & Kano. Quite the adventure. I had a good laugh...)

If in doubt about US charities - children, cancer etc are always worthy causes, and in North America the United Way is an umbrella organisation that does a lot for an incredibly wide variety of charities.
