When I look at an individual topic, I can unfold a list of individuals who have posted on the topic, and the number of times they have done so: [image] Could someone please help me build a query in Data Explorer to determine: Average number of unique individuals per topic (day/week/month/year) T…

I thought this would be really complicated, but turns out there’s a handy “participant_count” column in the database :slight_smile: Top topics by number of unique participants over the last year -- [params] -- string :interval = 1 year SELECT id as topic_id, participant_count FROM topics WHERE b…

Thank you so much @david ! That’s a tremendous help! (And thank you @zogstrip for moving the thread to the right category. I’ll get my bearings eventually.)

Hi @david , Sorry for the very long delay. I do have some examples now. Sometimes the query is right, sometimes the count displayed in the thread is right. Sometimes they report the same number and are both right! I noticed that when the counts differ, the threads have had posts split off to new th…

[图片] southpaw: when the counts differ, the threads have had posts split off to new threads. I believe this is mostly expected. Important to note.

[图片] southpaw: I noticed that when the counts differ, the threads have had posts split off to new threads. I tested this functionality. I am unable to reproduce it. As I described in previous post the counts are differ (for staffs) only if the topic had deleted posts. [图片] southpaw: No c…
