Your quite welcome. Along with the Automation plugin recommended by @JammyDodger a couple of others that may work well.
The above plugin will allow a great number of things. In one particular application to your site. Might be a wizard that on sign up generators a pm maybe to a group(s) based on the new member’s interaction with the wizard. This would notify your day ‘ambassador’ group a notification of someone new with possible needs. The Wizard could also I believe guide a new user.to an introductory cat/topic etc…
Assign might also come in handy.
