First of all personally if these are the only 3 reasons why you should be Super Admin I don't believe that you're the best candidate. Besides the forums, good attitude and consistent activity is expected of staff members. In my opinion a person who wants super admin should be going above and beyond in most important categories related to staffing.
Secondly appeals are not something I take very highly I more like to see someone do 1 or 2 to show you are capable of properly handling a situation out of game as I don't feel they prepare you very well for demotion requests.
Lastly you just came off a long break so I feel you definitely need to get back your consistency.
Explain in detail how you would act in the following situation:
A staff member bans a user for an excessive amount of time, how do you approach the staff member to ensure that everyone is treated fairly?
I check the rap-sheet of the player and then would approach the staff member.
I would ask if the ban length seems appropriate for him and why he thinks it is. Then I would point out the appropriate ban lengths on the staff handbook.
Note that these "appropriate ban lengths" in the staff handbook are recommended not required.
All in a all you've been a good admin that I've known for a while but I feel that you have a bit to go before you are ready to get Super Admin.
