This has probs been brought up before - but I think It would be good if you had the option to "follow" threads on the forums.

e.g. your selling thread, or just one you're interested in.

This function would send you an alert every time a new reply was posted on said thread. I would personally find this very useful.

Any supporters out there? 

Oooh yay! I'm very glad about that - I always lose threads too.

Can't wait for V3! xo
