The biggest change is that we've added user logins. You can now register for a free user account to get a more personalized experience.
You'll also notice a new updated forums section with trackbacks & user posting statistics.
In the near future, we'll be adding even more features based on the new model, including the ability for registered users to easily submit new links & content and get recognized for it.
If you have any trouble while using the new features, please contact us.
cheers! -Jason
