This is entirely a decision for your school.
Many schools prefer to control the page in the interests of branding and student privacy. For more information on privacy guidelines from the eSafety Commissioner, see here.
CrowdRaiser has been developed to allow all CrowdRaisers for a campaign to personalise their page and edit this public page thereafter.
However if you choose to have more control than this, and allow CrowdRaisers only editable by a nominated person in your school, GiveNow can help you with this.
