Digital systems overview

Provides a high-level overview of the all digital systems used within the club (i.e., member-facing systems, systems used by the board, systems used by the social media team).
TODO:
AllUnited
Wordpress website
Mailing lists
Gmail accounts
WhatsApp group
Social media accounts
Should the systems be documented in the individual roles, or in a central place here? Or both?
I think both would be helpful (but making sure the vol pages have a link to this page, so that we can use back-refs to find it again)
