No, it doesn’t.
You don’t “upload” anything in a WordPress installation. You write. And “users” (depending on their level) can submit a post for review. You or another admin can approve it for publishing. After you will get more familiar with the tool (=WP) you are using…
I see, but I would need something that requires “admin approval” before posting otherwise maniacs will be posting links to porn sites all day long and not short stories. Agreed?
