Organizations and individuals are encouraged to advance the work of Open CSA by underwriting specific activities. Donors may contribute any amount. Donations may be used for specific purposes, such as to defer meeting expenses, produce educational materials, hire program managers, etc., or to support general activities of the Member Section.

An OASIS member organization that donates 5,500 USD or more annually (in addition to its OASIS Foundational- or Sponsor-level dues) may have its logo linked from every page of the Member Section's web site. See the Member Section Supporters program description for more details or contact OASIS Member Services.
