I'm somehow getting unsubscribed from a thread I have set as instant notification in the Miles Buzz forum (the Marriott tweeting thread). Can't figure out why. I keep resubscribing, and it keeps dropping off. I get a few emails then it stops, and no longer shows up as a subscribed thread. Does not seem to matter whether I access the thread from my phone, my ipad or my desktop computer.

Any idea why?
