Pam Migliore wrote to the ixdg list with a query (below) about international
customer visits. I've had the pleasure of knowing Susan Dray and David
Siegel of Dray & Associates for nearly twenty years. They are incredibly
experienced with international usability research and have been teaching
about it at CHI and UPA for as long as I know them. Susan can be reached at dray at acm.org and http://www.dray.com.
