Nihonto Club

Ability to send private message (PMs) to other members is available again. Your mailbox is available in the menu on the left hand side (Messages). If you would like to contact somebody else, you may either use Write new message option and pick a recipient, or use the link Send this user a message on the member's account page.
If you don't want to receive email notifications when somebody sends you a PM, disable the flag Receive email notification for incoming private messages in your account.
