Btw, Tony! I dunno if it's a bug or not, but like... In this version of xenforo, if you stay away from the forums' tab, you never get notified if you got an alert or something.
I either need to be typing something on a thread, or to have some sort of activity (refreshing the page, liking something, posting something... Anything) to get notified of a new alert.
How often are you trying to PM that you'd run into a time restriction?
