I just want to report that my email notifications haven’t been working since yesterday afternoon for me, on threads and PM’s.
I know my email is working fine so I’ve eliminated that angle so I’m just highlighting this issue now.
Thank you! 
If you PM me your email address I’ll make sure it’s not on a black list. That seems to happen occasionally (not our blacklist - we get onto your ISP ones somehow).
ooh ok, thanks Sarah, I’ll send it onto you now
