One last comment - I think I understand this as follows - if I start a thread and get a response I will get an email unless it is just a thumbs up then an alert; if I respond to someone else's thread I will not get an email but will get an alert. Anyway that is how it seems to be working for me. I get emails on my thread but not on my responding to others - I just get an alert. This is o.k. just want to be sure I understand.
