    Clustering users according to their activity

      Hi everybody,


      I have a table that looks as follows:

      - Message Id

      - Message created at

      - User id


      Now I want to show how many percent of the users created a message in the last week and how many users did not create a message in the last month (some kind of "clustering users" according to their activity). How can this be realized using expressions?
