I received the following email from FamilySearch Support:
Dear FamilySearch Patron,
Effective 13 February 2008, the Collaboration E-mail List feature on the FamilySearch.org web site will be discontinued. You are receiving this notice because your e-mail address is listed in at least one of the collaboration groups. Please ignore this notice if you are no longer actively participating in these groups.
If you are actively collaborating and would like to remain in contact with other members of your group(s), please do the following before 13 February:
1. Send an e-mail through your collaboration group(s) to other members requesting their personal e-mail addresses.
2. Save their responses in your personal e-mail system for future correspondence.
Thank you for your continued patronage.
FamilySearch Support Team
