OSDev Wiki:Site support
Monetary donations are not needed at this time. The hardware, colocation, and bandwidth costs are covered by myself, Chase. If OSDev ever needs money to continue operation or purchase new hardware a notice will be posted to the OSDev forums. What we need is people dedicated to updating and maintaining this wiki and answering questions on the forums. If you really want to donate money to something please consider a donation to the American Cancer Society.
