Over at the Global Education Collaborative, I've posted a link to a Google spreadsheet where you can post and locate projects online. The GEC has really needed a better method for organizing this information, and I think the document will serve as a central location for finding projects. I expect people will be able to sort projects according to certain criteria as well.
I've embedded the form below. If you haven't tried Google Spreadsheets live forms yet, you simply must. It's a fairly easy method for creating your own surveys.
