Probably a larger task but giving contributors the option to either receive automatic campaign update via email. Or allow them to optionally create an account on the funding platform to manage their contribution, such as changing funding amounts, changing reward options and changing their funder listing display. I would suggest using Mozilla Persona and or OpenID/OpenID Connect as an easy way for contributors to login to such an account.
