What is the best way to increase my reputation and privileges?
I am new to Stack Overflow, and I'm currently learning Objective-C with the Big-nerd-ranch guide. I have visited Stack Overflow repeatedly while learning Python with Zed-A-Shaw's Learn python The Hard Way. I have to say, I couldn't have done it without the help of Stack Overflow.
I decided today that I'd come here and try to help other beginners with problems I had encountered myself and hopefully become a valid member of the community. I stumbled upon the chat rooms, specifically the iOS beginners room, which I found has a 20 reputation requirement to use. As a new user/programmer with limited knowledge, what sort of things can I actively do in the community that would help me gain this reputation? I do not want it for free of course, I just want tips of what someone like myself can do to help.
TL;DR: I'm a new user with limited knowledge of Python 2.7 and Objective-C, what can I do currently to help other users and gain the reputation required to use the beginners chat room?
