So your saying that I cant just Hold a Challenge to Find a admin? Again What would you so to find them.
I wouldn't SEARCH for them. I would just see who I could trust to do a good job as an admin.
Generally through two ways:
-While hosting, don't give anyone admin. See how they act over maybe a month's time. If they're obedient, and often inform you of people who are breaking your rules and never wrong about reporting, then it's a good admin.
-While playing in other servers, see whether or not the admins are abusive there. If they aren't doing their job, keep this in mind. Never let that person be admin.
