Interesting how many of these "big guns" don't like making e-mail addresses available. Lot's of physical addresses and telephone numbers, but, as for easy to use e-mail, some are quite aloof. On the other hand, others are much more information and communications technology friendly. :-)
Pisst. Don't tell anyone that I'm spending weekend free time mining high level corporate e-mail addresses.

I spent a few hours "mining" yesterday and today, and I've got some 250 or so (only scratching the surface), high quality, executive level, corporate contacts - many interestingly enough from Europe - to use for a test run on Monday.
