I figured that whoever wishes to be the new Admin in this wiki, they must meet these criterias:
1) The Admin must not be a 'Powermonger', someone will abuse his/her position and authority as an Admin.
2) If an Admin responds to a message from any Wiki user, the Admin must reply back with a neutral or friendly message (whatever suits best). The Admin must NOT however come off as rude or replying with words such as "I don't care."
3) The Admin must not shame any wiki user on this page over past deeds. If any Wiki user constantly causes trouble, the Admin is allowed to block that Wiki user as a penalty if decided.
I'm sure there's a few more criterias as well, but these ones I mentioned are pretty much expected of someone who is willing to take responsibility as an Admin of a Wiki.
