Hi, Google Code-in is about to start:
http://www.google-melange.com/gci/homepage/google/gci2013 https://www.mediawiki.org/wiki/Google_Code-In
We have currently 72 tasks published and 13 mentors. We are still looking for more mentors and tasks. If you are interested, contact me.
This is the first time Wikimedia participates in this program and the only certain prediction at this point is that we all will learn a lot.
We have been warned that especially the first two weeks will be quite messy, with many impatient newcomers landing in our community channels and asking for help / feedback / review. Please be kind with them. Things will eventually settle down, partially because our documentation will be better, partially because the students interested in Wikimedia will be familiar with the basics and will know where/how to ask.
Ideally https://www.mediawiki.org/wiki/Google_Code-In should contain answers and links to answers for the frequently asked questions. Try to answer GCI students with links to the appropriate pages, and try to assure that such links are available at our GCI wiki page.
Thank you for your patience. I have no doubt that your direct or indirect help will pay off with better documentation for all kinds of newcomers interested in many areas of contribution.
/me goes to prepare a hot beverage. It is going to be fun.
