The main calls to action are register and donate. Would be great to also have a feature to "Volunteer" where you could accept volunteer registrations, segment by type of volunteer opportunities (customized by nonprofit), and communicate with these constituents. Many people are needed to run event day logistics and would be great if they could be recruited, tracked, and managed within the event management software. Prefer not to make them a participant on the teamraiser, as some volunteers also need to register to Walk.
