MOSA Handbook

This handbook documents how MOSA operates — our processes, guidelines, and resources for board members, fiscal sponsors, and community contributors.

  • Onboarding new board members (coming soon)
  • Financial processes (coming soon)
  • Communication channels (coming soon)

MOSA provides fiscal sponsorship for open source events and communities that align with our mission. As a fiscal sponsor, MOSA:

  • Receives and disburses funds on behalf of the sponsored project
  • Provides a 501(c)(3) umbrella for tax-deductible donations
  • Handles tax filings and financial reporting for the project
  • Provides organizational credibility to donors and sponsors

To apply for fiscal sponsorship, contact us with:

  1. Description of your event or community
  2. How it aligns with MOSA’s mission (open source, Drupal community)
  3. Expected annual budget
  4. Geographic focus
  5. Current organizational status

The MOSA board reviews applications at regular meetings.


MOSA can provide the following support to fiscally sponsored events:

  • Financial management — receiving sponsorship payments and paying event expenses
  • Legal coverage — operating under MOSA’s nonprofit status
  • Insurance — event liability coverage (where applicable)
  • Accounting — annual financial reporting
