This would make things a lot easier
An option to allow users to be notified only of replies to themselves on a world's forums would be nice. Some people don't want to see every new post in a thread, but it's kind of the only way to be notified if you are replied to. Otherwise you have to hope you remember to check.
+1 I honestly think this would be super useful with like. normal forum threads as well, especially in regards to forum games. I think the forum threads work a bit differently than world threads, but maybe just a "1st user to post after you" option would be nice?
