Signing the Honor Code is not a requirement for becoming a member of WikiTree. After being confirmed and you wish to edit open profiles then you would need to sign the Honor Code but if your only interested in adding your own family and Ancestors and not working on the open profiles that other member created you do not have to agree to and sign the Honor Code.
The confirmation for WikiTree comes to you as an email, so you may need to check your inbox and spam folder. If you cannot find the email, a new confirmation email can be generated at E-mail confirmation problems.
The other option is to Click here to go to your Home Page to finish adding tags, tag comments and volunteering by clicking the add tags and volunteer button at the bottom.
You can only work on your profile until you add tags, volunteer and are confirmed a full member.
