I helped setup www.350.org.nz for a group of young people working on
climate change and we need some rails developers to help add features
in the next few months.

The site is built with BrowserCMS (http://browsercms.org) which is a
new cms that is pretty basic but gets the job done so you'd get to
play with that.

We have a good designer on board and a few templaters so it's mostly
just backend rails work that we need help with.

This campaign is being run by volunteers so there's no budget
available for the website, we're all just doing what we can to get the
word out there.

email me at joshua at 350 dot org dot nz if you're keen to lend a hand
and i'll add you to our basecamp account.
