I thoroughly read the Wiki-article on non-profits that Woodstock cites and then went to one of the refs at the bottom of the article:
http://www.idealist.org/if/i/en/faqcat/26-24. It has lots of information on non-profits (actually, more than one would probably ever want to know)...
That makes it even harder, because setting up a non-profit is actually a lot different (and possibly harder) than setting up an e.V. but I think that at this stage, choosing terms for the US and Australian readership that capture the essence might be better than contuing to lose sleep over the issue.
So my question is: what do all of you other professionals think about "non-profit" for the Americans and "incorporated association" for the Aussies??
(it does make it hard to give points, too - does anyone have experience in that??)
