3W = who what where, that is if we want to track information on what which of our users (=organisations) are doing where. However, I thought Sunflower is a community management tool, so the focus would be who of the contributors does what. Do we really want to track 3W information on user organisations, and if yes - who's going to maintain that data? Do we at all have a mandate to track such information? (Doesn't seem right to me, to be honest - especially not if we don't continuously maintain those data on behalf of the user orgs). Too me, it's too much data. Too much complexity.
