I searched option for getting notified when some questions asked by others which I'm interested in get answer(s). I came across this situation every time I found some intelligent(good) question and even I'd like to know the answer. The conditions are.

1. I like the question and I've not left any comments to that post.
2. Even I've not tried to answer that question.

But can I get notified when it get some answers,

1. Even if they don't address my name using @ ( if in case i've left any comment). I saw this symbol at the right bottom of the question page that question feed

If I go to question feed it ask for subscription to google and those options are strange. I just want to get notified within Ubuntu forum(like we get notificaions) for answers answered to some others question. Please suggest even if there is any alternative method. Please help me.
