welcome jingda. you can always help people in any section just state that the help you are rendering is for mac users. But you didn't tell what field you are into whether hardware or software. you should do that so that people would be able to assist you on what to do.

Have just created a website but is not open to public so i can give people feedback about their website. good in networking. Hope to see you guys around and have me in my threads
