I've been lurking here for quite some time, always intended to put in some help but life always seemed to get in the way. As for a group, why not set up a non-profit to support widelands itself, pay for servers, and build systems (maybe something like a jenkins server to automate builds for distribution). Why give the money made by the widelands organization entirely to another group, when widelands could use it to improve itself, as long as it's not taken home as profit, or pay by a chairman then it's quite legal. A non-profit CAN make money, but it all must stay in the company or to pay for services the company needs to maintain itself or offer it's product/services for free. On that note, people can be paid employees (all this is coming from US law, I've done quite a bit of research into starting an NPO), but the director, and board members CAN NOT get paid (the people who control the money can't pay themselves to do it), but can hire in personnel (programmers, graphic artists, sound people, server admins, whatever the case may be) who can receive a salary.
