Want to see a list of who is in your channel? Nectir shows you a list of who is online in the Nectir workspace, as well as a general list of all the members in that particular channel.
To see your members list, do the following:
Go to the "Members" icon in the top right corner of your channel. It should look like a group of people together.
When you first click on it, you will see a list of all members in your channel. (green for online, yellow for away, red for busy).
Toggle the list from "All Users" to "Online" to see a list of those who are currently online.
