I believe I am qualified because I have helped this wiki in many ways including adding/removing templates, adding info, correcting grammar and removing/adding punctuation.
My best contributions IMO are the correcting grammar ones because if our articles don't have the correct grammar, people would think that our other articles have grammar issues and further believe that our wiki is poorly organized/made.
Yes, but rarely. Usually it's a vandal vandalizing.
I plan to warn users in a polite manner if they have done something wrong, assist users more, protect pages, revert vandalism and block
