Look on top at the tool bar that says, "Thread tools". Click on it and it sayson the bottom line, subscribe to this thread. Do so. Now to find it, you go all the way up to the dark brown tool bar, where it says welcome. Click on Settings, now it opens a different window. From here you click subscriptions, click on it again. Your last posting or thread you have subscribe to, should be on the top.
I hope I did explain it understandable for you. I'm still figuring out things myself, as so many others here too. Hang on in there, it all takes time and a little bit more patience.
