Other forums (GameFAQs, Anandtech, etc.) let you see if someone has replied to a thread you’ve posted in, but I can’t find that feature here. Maybe I’m just missing something obvious. Is there a way to sort your postings to see which ones have replies since you posted or maybe enable notifications (in the forum) to see replies made after you?
In your User Control Panel go to Options and there you can set how you want to be notified of replies.
