TO follow a thread, scroll to the top and there is a watch button. If you are already watching it, it will say unlatch. To un watch a thread you don't want to watch anymore, click, un watch. To save a post, look at the top of the post, there is a page number, something that says "new," and 2 other symbols. Click the symbol that looks like a flat almost, and that will allow you to bookmark it. You can share the bookmark, so when people look on your profile it shows them the book mark too, or you can make it private. Hope that helps!
