[META] Unity Answers Karma and Moderator Rights

Hi UA Community,

Could anyone bother to give me more insight on the Unity Answers Karma System? As of now, I have 1,062 Karma and have obtained moderator rights (to the moderation queue). My question is: When can I obtain other rights (like editing of answers, questions and closing of questions)? It isn't explained anywhere. Then I can work out how much Karma more do I have to earn to get myself satisfaction of joining the big league :P. Also I would like to use this question to thank all the Users above 10k Karma who took so much time to help the Unity Community!
