1. When is double posting okay?
It is discouraged, but allowed for in threads that update themselves. Things like the Signature forums threads (eg, Polaris, Owen, etc), news (my KHII thread was littered with double posts), and Frontsite updates (again, I littered the thread with multi-posts).

2. What is the signature size limit?
550/250 L*H in pixels. Includes text. 50 KB for images.

3. When should the warn button be used and when should it not?
To notify moderators of rules-violating posts. Obscenity, rudeness, and things of that sort are Warnable. These Warns should not be used to directly argue with the person at fault, as there is no knowledge of the warn to the offending person, nor should it be used to personally chat with a moderator; they (shouldn't) know, either.

4. How can a banned member get unbanned?
Two years appeal, April Fool's Day, or the Fencing Cactuar exception. Accidentally banned members may make an immediate appeal to the moderators right away if they have a good case.

5. What is EoFF's policy on cursing?
This forum is open to both children and adults. Though cursing exists, it should be used sparingly. Excessive, nuke-chained insults or derrogatory uses are not encouraged, and may result in warnings.

6. Psychotic has found your old second account but thinks it belongs to crashNUMBARs. Would you, and if so how, inform him of the discrepancy? You still want to use the account in future.
Hold up, Psychotic found it? I would argue that he is Psychotic, and let's face it. It's Psychotic.

On a more serious note, I would provide a reason for which the account was used (something like a competition where you needed to masquerade as someone else). Not that I would be found in this situation; if I want to tell someone something, I'll just tell them.

7. crono_logical is injecting javascript into everyone's posts that makes pictures of penises and vaginas (nonos on eoff!) pop up on every thread. How do you confront him and get him banned, him being an administrator and you a lowly Cid's Knight who can't ban admin?
Make a thread in the staff forum and provide screenshots. This hypothetical situation must hypothetically be made knowledge to the rest of the Staff, who are capable of resolving justice.

8. rubah won't shut the smurf up. You're really tired of her spamming everywhere and you think it's giving the rest of the staff a bad, if rather active, name. How do you tell her children are better seen and not heard?
Most likely a personal appeal via whatever contact method is available at the time. Taking into circumstances, if EoFF hit a recession, I would encourage the posting to at least stimulate activity, even if it is mostly "omg w3 haet j00z rubarhb" threads. Ignoring that I would just tell her to shut up and give a rational explanation accompanied by reasons for it.

9. Hsu hasn't performed a moderative action in a year. Pick a course of either trying to drive him off staff or drive him to activity and state how you would do it. Assume that Loony BoB is on your side and no one else is.
Sup kikimm?

Again, I would post it in the staff Forums and make it knowledgeable to the powers that be. I would follow on the argument that inactive moderators are not conducive to a dynamic online community, especially when people might send requests to him without an expectation of response. A year is already enough.

If I wanted to be a jerk, I might just tell Loony BoB who is on my side to just remove the CK status unilaterally. If he hasn't been on, I would suspect that people would not notice. I will ignore his relationship with rubah.

10. Congratulations! You've just been made a Cid's Knight and you've decided to host a EoFF meetup at your house to celebrate. While you and your fellow EoFF buddies are partying it up, several people manage to browse a bit through the staff forum via your personal computer. What do you do?
This would never happen to me as I have no friends, but okay.

I would find out how much they know (internet logs, anyone?), what they know, and how severe it is. If any such information could potentially compromise the Staff in a manner, that person(s) would be confronted and most likely banned on the spot.

In a more ethical manner, I would request to remove myself from Staff for having allowed the trust placed in my station to be violated. I would also let my failure be known to the remaining Staff and work to ensure that justice be resolved.
