Need to configure your opportunity to only accept a limited number of applicants? No problem!
If your opp has specific dates you can select the "Sing Up" option
Each time a volunteer connects with your opportunity, the number of available spots will be reduced until all are filled. At that point, your opportunity will no longer show in the search results.
If you'd rather not limit the number of applicants leave the option 'Express Interest" selected and you'll keep receiving connection until you deactivate the opp or it expires.
