We do need help, so if you have something to offer, we'll gladly add you to the list of sponsors.
You can use the SourceForge.net donation system to donate money to individual developers. Or check the developers page for individual wishlists... In turn you will be listed on this page, of course!
If you want to donate a larger amount of money or have something else to offer (soft- and hardware, publicity, hosting, ...) then get in touch directly with either Karsten Dambekalns or a developer of your choice.
