[EasyDiscuss] Questions and answers can be moderated?

I have a few questions before purchasing:
use the rew
rite native Jomla, how it behaves EasyDiscussion? the url is seo friendly?
when one writes an application can not be registered?
I can make sure that when you send a question that is not published automatically, but only my moderation?
I can do so that it is only the admin to be able to respond?
there is a module
to display the latest questions? perhaps with the title, and only a part of the application?

thanks a lot
