You can become a supervisor on Answers by getting into The Initiate's Program (TIP) and completing the assignments given. To qualify for TIP, you have to be a contributor in good standing and not subject to serious disciplinary action.
Contributor badges are earned by simply answering questions, editing answers etc. Supervisor badges are given (by a higher supervisor) when someone is nominated as a category supervisor.
To become a supervisor you have to be nominated by someone that is already a supervisor. Then other supervisors will evaluate your questions, answers, and other actions. You can ask a supervisor to look over your activity and nominate you.
If you would like to get in touch with a supervisor consult the one in the category you are having issues with. For example I could be the lead supervisor for "Answers" for instance. You contact me and I would be able to help you.
