For a proper bounty project to be set up via either MorphZone or WArMUp, you would need to define a description of what would be delivered so donors know what they would get.

bigfoot had shared this link: MorphOS OpenGL 2.1 status overview

Alternatively, there could be a "self-managed bounty", which would involve bigfoot simply setting up a Paypal link (or a link to a similiar payment service).
