Would it be possible to use these Tag Groups to organize the Tags page, or sidebar block?
Here’s a quick before and after of my community I hacked with the HTML.
Rationale
more-neighbours-yyc is an organization
housing, planning, development, land-use, etc. are that organization’s interests depending on the topic.
Separating the categories on this page would help users feel more confident tagging their posts, and in navigating our forum for these different tagging purposes.
Someone from more-neighbours-yyc posting about development would be likelier to use both. So, a new user interested in development, could use the “interests” tab on the tag page to find the topic posted by more-neighbours-yyc, without needing to search for, or even know about the organization!
