Like right now. How do I go back to the main thread? I see your reply to my reply, and I am replying to that. But can't find where to go back to the master thread where all the other replies are.

Welcome! I foresee a grim future for Facebook. I haven't posted anything here yet, but I'm quietly building up my network of people I had on my Facebook friends list, for the day FB goes "poof."
