Hi Mark,

Thank you for self-certifying for the Pre-1700 badge! Participation in a Pre-1700 Project is strongly encouraged for those wishing to edit Pre-1700 profiles. Collaboration is essential because pre-1700 ancestors are shared by many descendants.

It looks like the United States Project would be a good fit with the tag you entered. Adding the tag United_States will help you get updates about activity for that project.

Do you have any questions? Let me know. I'm happy to help! :-)
