Redirect a user to read a PM upon registering?

I don't know if there's a mod for what you want, but there's this mod: https://vborg.vbsupport.ru/showthread.php?t=267180 that makes notices a lot more visible. You could probably modify it if you only want it for that first PM.

There's also this mod: https://vborg.vbsupport.ru/showthread.php?t=186886 . I don't think the private message page is on of the options but it probably wouldn't be difficult to add it as one. Edit: actually this ones for vb3 so I'm not sure if it works with vb4 but you could try it.
