Daniel-
In page deletion, a sysop decides that a page is worthless and that they don't want it there. The sysop deletes the page permenantly and then all records of the page are deleted from the server. An example of this is the contravercial [[Fuck you]] page.
Wrong.
1) Deletion is *not* permanent. When a page is deleted, it can still be restored using the undelete function.
2) Sysops only delete pages on their own determination in cases of *obvious* nonsense (AKA "crapflooding"). Whenever there is even a hint of doubt, the page "Wikipedia:Votes for deletion" must be used instead, where pages to be deleted are listed and picked by sysops (you should not delete a page you have added yourself).
A sysop really does not have much room to decide "that a page is worthless and that they don't want it there". Rather, he is more or less a servant of non-sysop users who want certain actions which are a bit harder to revert than simple editing to be taken. Sysops are *not* editors.
Understanding this is really essential to being a sysop. Do you see how a quiz can be useful now?
