Yeah, what WCA says.
When I go to that page what I really want to know is, has anyone replied to any thread I’ve posted on since I last looked at it.
The “No replies since” at least let me see which ones I’d got the last word in 🙂
(Ideally I’d like any threads that the current user has contributed to, to be gently highlighted on the main thread list and then maybe have a badge or extra highlighting if there have been new replies since he/she last read it – but I realise that is a logistical nightmare to code and manage)
