I would really like to see an option much like the current "View New Posts" option where a user can opt to click on a link that would show them all replied topics to their posts. For example, if Bob creates a topic and then makes a post in another topic and then logs off, and two more people make a post after him in the topic he created, and one person posts after his post he made in the other topic; when Bob logs back in, there should be a "View New Replies to My Posts" button and it easily shows who replied to his topics/posts. I think this would be a really helpful and necessary version for a future version of IPB (possibly v3.0).

I like it. I would find it very useful. I usually search my own posts if I need to find out whether someone has replied to the same topic as I, and this suggestion would make things much easier.
