Hi Shelley. You've signed up under our new Guest Membership program. Guest members can only edit their own profiles. This gives you a chance to try it out before committing to managing a tree here. If you want to contribute your tree, just follow the instructions on your profile to Volunteer. Be sure to include a comment making it clear that you're willing to contribute to the tree, and one of our Greeters will confirm you. Then you'll be a full member who can create and edit other profiles.
Welcome to WikiTree! :)
