ps. how can i lock a topic?

You can mark all forums and subforums in this users moderation-permissions (Users & Groups / Users / Permissions).

You can lock a topic if you have moderation permissions in this particular forum/category (this includes admin of course). At the very bottom of a thread, you will find some buttons (delete, garbage, move, lock... etc.) and the quick mod tools menu ("lock this topic").

If you are not within a topic but in a forum, you will find a link "moderate this forum" at the bottom. click this and you can also lock/moderate several topics at once.
