Phil can probably give a more thorough answer, but I think,you can set watched forums and other notifications under your user account on this new site.
The whole thing takes a little getting used to, especially if you used the app on an iPad previously. But I am starting to learn where things are, and how to set things up (I don't have to log in every time any more!).
And I asked Phil to add a navigation link at the bottom of a thread to take me back to the list of new posts...and he added it yesterday. Look for a link,that says "Recent Activity" at the bottom of any thread you are reading, and it will take you back to the "New Posts" list. Very convenient way to get to a new thread once you have read to the bottom of one.
