I had real go at them directly, so hopefully this will not change. 

I thought they fixed this, but it's been removed again. Also the Earnings tab is reporting Forward PEs as zero, so they have stopped calculating it completely. 

I concur, this is the most important piece of information I use. It shows that the people at Seeking Alpa really do not understand what investors look for.

Same issue here.

Same here.

I agree this is annoying, I haven't found a way of switching it off.

Thanks George, interestingly enough I seem to be still getting all my e-mails today, so I think it's all good.

I got a message again this morning in the user interface to say the message have stopped and to re-able it via the button click. Has anyone else got this message?

They are coming through properly at my end. It started off slowly, but all good. @huffster22 you may need to click that button in the web interface to re-enable mail notifications.

So for me the situation seems to be improving as the volume of e-mails has improved. I am not entirely sure I am getting all of them, but much better than before.
