Involuntary unsubscription from thread
 

I noticed that I had been involuntarilly unsubscribed from the daily notifications of the SIN DO 2014 thread. I did not unsubscribe from the thread but it was not in my subscribed threads folder. Had to subscribe to it again...

A shot in the dark but did you post to the thread via a mobile device and then have your subscription drop? I've noticed that when I post to a subscribed thread via my iPhone, my subscription to that thread drops immediately after I posted. I've notified IB about this and they are "looking into it" but I'm not holding my breath on a fix.
