Do think about it, and jackie, if you are worried about outgoing mail, you could put all the US cards in a box and have someone here put them in the U.S. post for you.

If you're worried about receiving the cards, though, that I don;t know anything I can recommend - I have no inside info on the Spanish postal system!

Also, 50 cards isn't THAT much more than 30 - if you break it up into groups (I'll do 20 on Friday, 20 on Saturday and 10 Monday, for example, it's less overwhelming!)
