I have tried to send a poster a PM and got "Sorry. We can't deliver your PM as this user is currently unable to receive PMs."
I am certain as I can be that the poster is not banned. They did post a while back to say they wouldn't be posting for a while as they were in a bad way and I just wanted to know if the poster was okay. I assumed that not posting for a while meant just that but they would still be registered on the site and would be able to receive PMs even if they didn't log in to actually look at them.
So I would just like to know what the reasons would be for why I got that message. If someone de-registered from the site would you then get that message for example.
Thank you.
