# in Conversation (LIQL Query) from Messages
Hey Khoros Community Gurus, I'm trying to figure out how to get the '# in conversation' number using a LIQL query. I get the other stats, but am not sure about how to calculate the number that is sh...

I think that number refers to number of unique users participating in the discussion right?

I still don't see a better/more efficient way than getting all message authors in a topic, then loop over all of them and aggregate an array (sequence) of unique authors... pretty terrible performance wise when the topic is long (e.g. a lot of messages to go trough).
Hey luk - Yeah, I had the same issue when first starting out on this journey and satya was able to suggest that we use topic.id as a solution, however our moderator has moved posts and this 'broke' the query when using topic.id. So am now returning to figure out the best way to get the details from a post that mimics the '# in conversation' if I go back to using just id.
When using topic.id our middleware person sum up all the child threads to get the number of people in the conversation, but now if use 'id' instead of 'topic.id' I can't get those details. Oh hum. I suppose we could do two queries?
Need to dig around to figure out how to get '# in conversation' even if the message is moved by the moderator. Tricky, eh.
