If you look down the right-hand side of the screen - There should be a list of the supervisors for the category. Just below that - there should be a blue link 'Become a Supervisor'. Click it - and follow the instructions.
Well, it is mainly up to you, Don't forget, a Category Supervisor looks after certain categories, whereas a floating Supervisor maintains every category, just 'Floating'. Hence the name. So it depends whether you prefer just one category or not.
If a floating supervisor wishes to become a category supervisor, they can apply in the same way that a non-supervisor would, by sending an email to the appropriate email address.
You must be at least 15 years of age to become either a floating or a category supervisor.
No, you have to be a Category Supervisor in order to become a Senior Supervisor. (See the Related question.)
Because, being a Supervisor whether it's floating or a category, or a senior Supervisor, it requires a lot of responsibility.
Either is good. If you are very knowlegable in certain caegories, then you may consider being a category supervisor. If you knowledge falls into a bunch of categories or you don't want to be tied down to watching certain categories, you may want to become a floating supervisor. Note that category supervisors are not restricted to just their own categories - they can still work in whatever category interests them.
Yes, they can. Although in such a case, it's recommended that you consult with the current supervisor to see what he/she needs help with. Also, if the category is unsupervised, we hope that they'll become that category's supervisor.
You can e-mail WikiAnswers @ Answers.com (no spaces) asking to be either a category supervisor or floating supervisor. To be a category supervisor you should be knowledgeable about the category. Becoming a floating supervisor is a good way to start off. You can also post a message on Brave3's message board. He can promote you too. For more information, see the Related Link.
A Senior Supervisor is not like a Senior Citizen where once a certain age, they are deemed into that category. A Senior Supervisor is a Super that has made many valuable contributions to WikiAnswers and has been around for a while on the site.
Yes, you can edit ANY category on the site, if you are a supervisor, as long as you don't upset another supervisor, but they should be glad for the help.
At the present time, only category and floating supervisors are able to get a WikiAnswers email address. If you'd like to become a supervisor, check out the requirements at: http://wiki.answers.com/help/become_a_supervisor .
Perhaps Ganderton (Gregg), the guy who made you a Supervisor. And the people who recommended for you to become one.
