Notification for Private Message

[induslady]

Hello,
Thanks for your response.

Yes I do have different user groups for Private Message Users and Non-Private Message Users, with Private Message Users having user title and their user name displayed in a different font color so that it is easier to identify.

Btu my question here is Private Message User, say X should be able to send messages to a Non- Private Message user, say Y too. X should be able to sends a message to Y, when Y logs in he should get the notification, say in his user profile page that "You have received a Private Message from X. However you need to sign up to read the Message".

Let me know how to go ahead and set this in my forum.
Thanks in advance.
