This has been discussed previously, but would the ability to identify threads that you haven't viewed yet be useful to anyone? That's a pretty common feature on forums and can be handy, but I'm not sure we have enough activity to where it's an issue for anyone at this point.

Likewise, what about the idea of being able to quickly identify what threads you've participated in?

I would love a feature like this. And maybe when you're logged in, on the main page it could tie-in to the 'Forum Activity' widget?
