In the spirit of bootstrapping the Goat Farm Foundation as quickly as possible, we're using Google Docs as our resource library.
Our primary effort currently is to build a space for people to share solutions for specific nonprofit verticals or use cases using Salesforce as the solution.
You can see an example of a solution documented here: Project Example: Essie Justice Group (prison reform/support).
If you'd like to contribute your own example, please create a new thread on the Google Group with your submission.
Feel free to create your own Google Doc using the above example as a template.
