By design, SignUp.com does not require participants to have a registered account with us; they only need to have a link or invitation to the SignUp.
Once signed up for something, there are several ways participants can access their SignUp.com SignUp.
1. Click the SignUp link in any invitation, confirmation or reminder message. (search for mail@signup.com to find the communication)
2. Go to our Home Page at www.SignUp.com and and click 
. Complete the one-field form to be sent a set of fresh links to all active SignUps associated with the email address.
3. If you HAVE a registered account (with a password), Log in and click My Invitations to access all your SignUps.
4. By downloading our pro app "SignUp by SignUp.com" for iPhone or Android. The app will show the participant/volunteer ALL SPOTS across all SignUps on one screen.
