Is this the "fail" issue you have been sending me? I have asked the vendor to look into that. I've been told they're looking into it. Are you still receiving the "fail" notifications?
No. The "fail" issue is related to replying to the emailed notifications, and I certainly can't reply via email if I don't receive any notifications/subscriptions via email at all.
As an additional data point, a friend who uses RSS tells me that nothing from the "community" is showing up in RSS feeds any more ...
Holy [pron filter]! SUBSCRIPTIONS IS WORKING AGAIN!
I realize that you have no idea what went wrong, nor how it got fixed, but well done for randomly changing things and fixing the problem regardless.
(Hopefully additional random changes will not now unfix it ...)
(I'll have to reply-via-email to something, even if I don't have anything useful to say , in order to test out whether that function is working ...)
 - Yeah, yeah, OK, I know that many of you will say that I never have anything useful to say ...
Right, I successfully got a posting through using "reply via email" ...
(Hopefully I can stop having to use the Web interface for everything.) (Although I still have to use it to post Industry News and the latest "trouble" ...)
