I have had several instances recently when I have not been notified about additions/changes to threads in forums to which I am flagged as subscribing - in the past week or so this has happened for the Gateway Comments forum and the UKSI forum.  It is intermittent - for example last week I had no email for several posts in UKSI, but over the weekend Steve McWilliam's several posts were all notified to me immediately.

This has happened before - last year I had no notification of an R6 update in that forum, and it was not until the next update appeared that I realised that I was behind.

They are not in junk mail.
