If you mean us evil staff, then yes. Anyone who is on this page has the powers necessary to delete posts/threads, edit posts/thread titles, and sticky/unsticky threads in forums. Moderators, those with their names written like mine, have those powers only in certain forums. Everyone else higher than moderator can handle those actions all over PC.
Though honestly, we're really not scary. Just make sure to follow the rules. And the staff is here for every member to talk to and ask questions to, because we're here to help members and PC as a whole.
EDIT: And yes. If you have a new part to the story, you can post it and not get in trouble.
