Hi Andrew and Decoder00 -
(I work at OpenPlans, we are a core contributor to the Shareabouts project).
Shareabouts requires Postgres and doens’t work with MySQL, but Decoder00 actually only needs to set up the client front end, as documented here: https://github.com/openplans/shareabouts/blob/master/doc/DEPLOY.md
There’s an existing database/backend that OpenPlans hosts, http://api.shareabouts.org/. Since Decoder00 is setting this app up for a non-profit, we can give access to this backend. So, no need to get complex with databases.
Hope this helps!
