You can send a private message (or PM) to any member of the Viki community. There are two ways in which to do this.
From your mailbox
You can find your mailbox at the top right corner of your browser. Click the ‘Envelope’ icon to access your mailbox.
Compose a message. Click the ‘Compose’ button on the left to create a new message. Enter the username that you would like to send your message to, in the "To" field. If you would like to send a message to multiple users, separate their usernames with a comma.
From the user’s profile page
On every member's profile page, you'll see a ‘Send private message’ button just below their profile picture. Clicking this button will navigate you into your mailbox, and will allow you to quickly send them a PM.
