You will never get a notification through vb
private messaging system as we do not integrate with that.
we have our own messenging system.
In global options the messaging system must be turned on. Then under your mail settings select how you want to send email. Set it to use Both.
You and your users should get an email as well as a PM. Those are the messages your talking about in our navbar. On the site I showed you an example I have 17 messages all PM's about comments on a photo I posted.
