Overview of Guest registration
To use any of the features on Ancestry, a user must have at least a Guest registration. To create a registered guest account, click here. As a Registered Guest, a limited number of resources are available at no cost. These can be created by providing a first and last name and an email address. Registered Guest accounts have been put in place to allow members to:
1.Access certain free databases (1880 U.S. Federal Census Index; WWI Civilian Draft Registrations; and so forth)
2.Use the Personal Member Trees feature in any of the following ways.
*Build a personal member tree, whether from scratch or by uploading a GEDCOM file
*Share your Family Tree with family or friends
*View another user's Family Tree if you received an invitation from that tree's owner
*Respond to someone who contacted you, requesting permission to view your Family Tree
*View any record linked to a Family Tree to which you have been invited, provided the person owning that tree has some kind of paid account on Ancestry
*View any photos attached to a Family Tree that you have been invited to view

3.Email members who have chosen to share their email address publicly. (For information about how publicly viewable email addresses differ from the Ancestry connection service, please click here.)
4.Respond to any email sent, even if sent via an anonymous user in the Connection Service.
5.Post messages on the Ancestry Message Boards (and otherwise participate in the general Ancestry Community).
6.Access valuable family history resources in the Ancestry Learning Center.
