I have two questions.
1 - how can my app request publish stream like this, all in one screen?

2 - is it possible to make a app like two or more pages, I already can make people like using signed_request, but lets assume I'll get people's permission, is there any way to make people like a different page?
Example: after people "like" my page where the app is, I'll get permission, then my app use this permission to like a different page or url, any way?
