I'm still attempting to get the hang of everything here, as my application form was just approved yesterday. I have an issue with my profile...I can't write any wall posts. I tried clicking "What's on your mind?" a few times, as the website instructed me, but nothing at all is coming up. Suggestions?

Even though it's been quite a while after the release of Portal 2, the series is still going strong. Do you think there will be a third game in the series? Feel free to explain why/why not in the comments if you want to.
