Let me first explain what I want to do, as this might be an easier problem of what I am thinking. I simply wanna do a Hot topic list for my Forums. To do this I decided to create a View that would count the number of distinct users for each user. I used Aggregation to count the # of users that replied in every topic.

The next step in my mind was to pass this result to the Hot topics list View. This view would use the counter explained above to filter only those topics with a minimum # of unique repliers.

My question is... how to pass the result of the first view (which uses aggregation) to the second view?

Thank you!!
