If you ever wanted to create a family address book for all the extended family you can do so by running the Addresses report from FTB, saving the report as a PDF file and then emailing the file to a service like Ringya (www.ringya.com) which will then convert the data into contacts on your phone.
Full disclosure: I am the founder of Ringya (and am also a MyHeritage user since 2007)
I don't think that MyHeritage is happy about Your marketing message on this portal. And I'm sure, most of the users don't like to send address infos of the familysite members to an external company/person/whatever.
Address collection is a big business in this crazy time.
