To change your e-mail address simply click the "Edit" tabe on your profile), change the E-Mail Address field, and save your changes.
Please note that your e-mail address is your WikiTree login. The next time you come to the site you will need to use your new e-mail address.
You can edit the e-mail address of anyone in your Watchlist in the same way unless they're an active user like you. If they're an active user changing their e-mail address means changing their login. Therefore, the user has to do it themselves.
Currently you cannot delete an e-mail address. Since we use e-mail addresses as logins this would have the effect of making accounts totally inaccessible. If you want to remove an account simply contact us.
