Overview of what you currently participate in, and what you dont

Hey, I really like this concept, but am I the only who is missing a feature to see what I participate in, and what I don't?
For example if I got the front page, there's a bunch of contests that has the "NEW!" sign, but I'm already enlisted in the contest. It's confusing to scan through pages and see what you're actually participating in.

So if a future update would contain a kind of filter, or a page where you could see what you're participating in, and what you're not participating in would be appreciated?

Just so you don't miss a chance to get something you really wanted to try out, just because you didn't want to scan through pages.

It's an idea at least. Comments?
