Special on-site volunteer coordinator user / NoInfo
This is the NoInfo use-case. They need to at least have all the information of which shifts need to be filled on any particular day and the ability to sign up users immediately.
Ideally the signup would be a matter of giving an email address, if this links to an existing profile, great. If not, we should at least create a user for this email, we might need to gather some info, such as next of kin, but ideally the minimum we can get away with as we don't want to discourage volunteers by trying to take loads of info at NoInfo (this was a definite problem with Vroom).
