I note there seems to be some strange goings on regarding posts today.
Highlighted by Bethan49 who posted "Reality Hits" but cannot see it or the six responses, so posted "Where's my last post? !". At least one other person responded to the second post and I tried to respond to it. Now, I can neither see "Where's my last Post? !" or any of the responses. However, I can still see the "Reality Hits" thread just fine.
I originally got to the "Where's my last post? !" by clicking on it from a notification email I got. Since adding to the conversation (maybe) I just get an "embarrassing" message. Just to prove I could see this thread, no matter how temporary I can tell you that CLLCanada was discussiong IOS9 beta3.
Nick/Neil, are admin's aware of this problem?
