If you have many eager Participants and want to give as many people as possible a chance to sign up, consider limiting the number of Spots each person can claim (Premium upgrade required).
Start by going to the Details tab of your SignUp's Organizer view. (Login and in the My SignUps menu on your Dashboard, click the SignUp Title to open your Organizer view).
Scroll to the bottom of the page and select Limiting Spots then enter your preferences. Click the blue Update button to save your selections.
A limit may be set per SignUp, per Day or per Week (Sunday - Saturday) - meaning that each individual Participant (identified by their unique email address) will be allowed to sign up for a maximum number of Spots given the limit time frame you specify.
Important: If the SignUp is also set up with the option checked to allow people to Sign Up Others (family members, team members, etc.), then the limit will be applied per email address. For example, if the limit is 3 Spots per SignUp, a parent signing up her kids (who don't have their own email addresses) would have the ability to sign up a total of 3 times. If a coach was signing up team members that do have their own email addresses, she could sign up each person for up to 3 Spots each.
