For each Project exists a support thread in the Bounty-Bay of the Pegasosforum with updated status information like the bounty amount, information about the bounty progress, reached milestones, screenshots as a preview of implemented functions and so forth. Furthermore there is the possibility to donate to the bounty by PayPal. The donations are managed by the AmigaClub Hamburg e.V. and are stored on the PayPal account until the bounty is completed.
Additionally to the opened bounties it is possible by everybody to launch a so called self-bounty. To do that there are some terms that have to be fulfilled like the payment of a start donation to the bounty of at least 25 Euro. More details on that and other topics are written in the bounty rules that can be found in here.
Coders that a interested in taking a bounty are requested to get in touch with the Bounty-Team. This can be done through the support thread of the bounty or through e-mail to email@example.com.
I think that the only way to get a decent GTK->MUI wrapper in decent time was that MOS, AmigaOS4, AmigaOS3.x (and mayb AROS) developer joins in a single project and works togheter... That's the ONLY(and most intelligent) way...
