You've completed your own registration and now you want to register other walkers. From your welcome page, scroll down to the bottom to "Need to Register Another Walker?" and click the link.
You will notice that the team name and walksite has been pre-filled. Scroll down to "Your Personal Profile", complete the registration form and click "Submit" at the bottom. If you don't submit each profile individually, only the last walker you submitted will be registered.
Once you have successfully completed a new registration, you will be directed to his/her welcome page. Scroll down again to "Need to Register Another Walker?" to continue.
Note: If you have logged out before registering another walker, you have to go through the entire registration process for that new walker.
The March of Dimes strongly urges each walker to fill out his/her registration. It is much easier for walkers to remember their login information (username and password) if they are of his/her choosing.
