Google Summer of Code
So if you are a student and you fancy writing some code this summer you should go check out Google's Student FAQ and Plone's PLIP section (keep in mind that you can come up with your own idea, if it's great then we'll dance with joy and accept it!) and if you are eligible and keen, you should apply!
