Following has an effect even if you don't allow email notifications. Click Content near the top of the page, then Following part way down the left, then Discussions over to the right and up a bit. If that seems a little clumsy use these ready made links.

The first three show new activity in threads you've started, contributed to or are following. You'll automatically follow any thread you start or add to, but you can choose to stop following (useful if you realise you've joined a rant thread and now want to stop hearing from it) or start following a thread that seems interesting, even if you don't have anything to add to it right now. Following Discussions is probably the most useful way to tell if any thread that you're involved with has had an update.
Only the OP gets to award helpful and solveds. OP is short for Original Poster, whoever started the thread. Look, there's another one for the user tip. 🙂 You marked ManSinha's first reply as helpful, and then later upgraded it to solved. That's why you cannot award another helpful in this thread.
