Hello,

I applaud the brilliant idea of turning user profiles as nodes! I think it is just what I need, but I am having difficulties proving it.

I desperately want to associate users with taxonomy terms. I also want overviews based on this association, like:
What are the taxonomy terms for a particular user?
What users belong to a certain taxonomy term?
List all users with an array of taxonomy terms
See the taxonomy tree (like in taxonomy_dhtml) with an array of associated users
