You can send a private message (or PM) to any member of the Soompi community. There are two ways in which to do this:
1) From your mailbox
You can find your mailbox at the top right corner of your browser at forums.soompi.com. Click the ‘Envelope’ icon to access your mailbox.
Compose a message. Click the ‘Compose New’ button on the right 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 by hitting "Enter" after each username. Hit "Send".
2) From the user’s profile page
On every member's profile page, you'll see a ‘Message’ button near their profile picture.
Clicking this button will navigate you into your mailbox, and will allow you to quickly send them a PM.
