I also seem to be able to create donation drives. Although I can only make them for nubs and case moulds, and not for my personal holiday to disneyland. But still, doesn't seem like a good idea to have too many open donation drives.
Edit: Checking again, it looks the same as the screen if you go to 'donations' at the top and then hit 'donate now' so actually I think create->Donation makes a payment, not a new donation drive.
