Solution
Our solution was Splace - A combination of the words 'Space' and 'Place' which was the underlining structure of Splace.
Spaces would be topic for communities to be built around, like Travel for example.
Places would then be nested subtopics, and possibly even subcommunities, that are related to that topic, like Tips, Photography or Recommendations for Travel.
Posts can be made to a Place, self categorising it for user's to find, while also appearing on the Space level, allowing user's to get a broad overview of what's happening in the Space.
This structure extended to each user's profile as well, giving them their own Space and their own structure of Places as well - Allowing each user Spaces to be completely unique to them and represent exactly who they are and what they're into.
