I've always liked 37signals as a company a lot and today they just shattered my affection for them into pieces.
Teaching programming voluntarily
We're a small group of volunteers teaching programming at a university in Bulgaria. Today we asked 37signals if they would provide us with a free Basecamp account. The account would help us coordinate our team teaching efforts and let us provide the students with more knowledge more efficiently.
As we're not getting paid anything for this by the university (although students get credits for our courses) and as we don't have any budget for course expenses (on the contrary—we pay from our own pockets in order to bring Ruby, Python and Clojure to the curriculum), we asked for a non-trial basic account pro bono.
