We welcome donations to support our work! Ongoing organization expenses include our websites and domain names, equipment rental for the annual meeting, and so on. In addition, as soon as we have money available, we would like to hire a part-time communications and outreach coordinator to help us spread the word about open source software and OneBusAway to other transit agencies and beyond. There is also a long list of enhancements that we’ve love to make to our apps and systems as funds are available. The Open Transit Software Foundation is a 501(c)(3) nonprofit organization, so that donations to OTSF in the USA are tax-deductible.
