We are a small nonprofit that conducts medical missions and are looking for software to help us organize our missions. Your software looks like it could help us, but I have a few questions before signing up for a demo based on our core needs: 1. Can volunteers fill out their own profile that they manage themselves? As in, they sign into a profile and answer questions themselves. 2. Can we edit all the questions asked of volunteers in their profiles? 3. Can we AND volunteers upload documents?
