Hi,

This begs the question, where do we put it? We don't currently have a run time config file/directory, or a config table in the database.

Yep - it hinges on #24

I've been putting the file store config in the DB - my line of thinking was that if the information needed to be updated at run-time (e.g. to add config for a new user, to change existing config values) then the DB would be a good place for it.

Perhaps we need a general config table for some of these one-off values?
