Haha, Zoe! At the top of the thread, just below the page numbers there is a little box with an arrow labeled "thread tools." If you click on the subscribe to this thread option, it'll show up in your User CP whenever there's a new post.
Unless when you said follow you meant something else. Lol. Then I don't know, haha.
And also, yeah. Though sometimes outlines lie to you. The idea you write in them seems to work, but then you realize that when you actually write it out, it makes no sense or it doesn't work at all. That's frustrating.
