With your Aria event calendar, you tag an event as an opportunity for volunteers with a click of the mouse. Once that is done, your event becomes active for volunteers to sign-up.
Your volunteers can indicate they wish to help out at an event by signing into Aria and indicating their availability or through a form that you can embed on your public website that links to Aria's database.
You define what positions/activities you need volunteers for, what shifts and how many people and Aria does the rest. Aria will close out positions and times when full so that you don't get more people then you need. And our reporting tools are second to none in allowing you to manage those volunteers.
