Dear MyNSF Subscriber, On November 19, 2007, the National Science Foundation (NSF) will replace MyNSF with a new email alert service called "National Science Foundation Update." National Science Foundation Update will include subscription options for all of the document types currently available in MyNSF, and will also allow you to subscribe to new content categories, such as Images and Videos, Events, and Upcoming Due Dates for Funding Opportunities. You can still choose to have emails sent on a daily or weekly basis, and will have new options to receive emails immediately or monthly. You will also be able to temporarily suspend delivery of email alerts from NSF. The subscriptions you have set up in MyNSF will automatically be transferred to National Science Foundation Update. You will continue to use your email address to access your account. If you have set a password on your account, you will need to reset it for National Science Foundation Update. Starting on November 19, your alert emails will be sent from the National Science Foundation Update address and will have a different format. You may also log into your National Science Foundation Update account at http://service.govdelivery.com/service/user.html?code=USNSF at any time after November 19 to set your password or view the new subscription options. If you'd like to cancel your subscription to NSF content, you can do so at http://www.nsf.gov/mynsf/ through November 16 and at http://service.govdelivery.com/service/user.html?code=USNSF from November 19 onward. Thank you for your interest in the National Science Foundation.
