They have a signup for volunteers (http://coderdojonyc.c...) to send announcements and things, so if you know you'd like to volunteer in the future I'd go ahead and do it now. Otherwise, if you just want to try doing mentoring on Sunday and see if you like it, they'll be doing a mini-orientation and you can choose to sign up afterwards.
Free office hours for programming help - any programming language, all skill levels.The format is super simple: you come with your laptop, sit and hang out and code, and flag down one of the organizers if you have a question. That's it!If we can't answer your question, we'll find you someone who can, or at least point you in the right direction.
Note that this is a meetup for people learning to code. Experienced developers are more than welcome, though - we appreciate the help! Entrepreneurs and recruiters, come learn to build your own apps! For those hiring or simply interested in supporting free learning in NYC, we are open to sponsorships, so just reach out!
