#Mention a Team Member

When having a conversation in Zulip, it is sometimes necessary to call the attention of another member. You can alert ("@mention") other users with a particular stream-message from within the body of the message itself. Type @ and then begin typing their email address or one of their names, and the system will offer you tab-completions. The completed @mention will look something like: @**name**, and it will appear as @name in your posted message.

If you attempt to @mention someone who is not subscribed to the current stream, Zulip will ask if you would like to subscribe them to the stream:

You can view any mentions calling your attention by clicking on the "@-mentions" view in the left sidebar.
