Channel owners can view metrics on their channel. Nectir's analytics feature include number of message sent per user, total room messages, and more.
Go to the channel you would like to view analytics for.
If you are a channel owner, you will see an icon for "Analytics" at the top right.
Click on the icon, and a screen will pop up with that channel's analytics.
More to come on analytics! Have ideas on what you'd like to see, send a direct message to @Vicky.
