My profile settings have the button ticked to receive notification emails for PMs, but I am not receiving the emails. I am fairly confident they were not sent, as I run my own mailserver, and the logs do not show any connection attempts at the relevant times, nor from any sender with 'smartclub' in the address. If the sending address is different I can check for that. Not a major problem for me but I do feel a duty to report bugs if I find them!
