Sending a private message automatically to every newly registered user

[propertyhub]

Hi! We'd like to alert all new registrants to the fact that they should update their display name before making their first post. There are two ways we could accomplish this:

• Send an automatic private message from the administrator to all new users at the point of registration
• Display a reminder above the box that a user makes a post (either reply or new topic)

However, I can't figure out how to do either of these! Any suggestions for which of these would be best to implement, and how to do it?
