I think the forums are fantastic but the one thing I miss (from other forums/websites) is the fact that you can't see when someone has replied to your comment. With this feature you'd be able to see what someone replied to you about and you can then reply back again or contact them. I think it's easier to keep track on what's going on too. This is a feature YouTube currently has and it works a treat.
If this is already implemented and i'm missing something please let me know, if not is it possible to add? thank you!
