$Username in email subject

[ajmboy]

Is it possible to add as default the $username of a member receiving a notification email? What variable is the email subject line and will it pull the username?

If I want all email subject titles like: Username, you have a new notification.

Try using $user[username].

[TLCTugger]

Try using $user[username].

Where does one use this text to affect the behavior of the forum's automatic emaiing?

Thanks,
