quick search (curiosity: in France, we speak about association, law since 1901, always need papers, smal cost without yearbook/directory...)
http://www.wikihow.com/Start-a-Private-Foundation
Some steps are optional... problem always come when there are money, taxe and papers because of potential profit...
Do as you wish, but we need a name, AHK, AutoHotkey, AutoL or rebrand, will depends of vote and your taste (in my opinion Lexikos must have the last word about program name..., but he don't want to share his real opinion atm, for me it is a problem, he prefers V2 or not ?)
For example, if a foundation is too complicated or huge to maintain (can cost extra $ to be in info register book or other option), we just need one guy as Tank did who pay domain and server (a forum don't cost a lot, it is not a upload/download platform, database are small, small donation can be legaly gave to one private person without problem or registration to a state just with paypal), and share server and domain password with lexikos and fincs or other (trust as friend, just in case when they are problem if not admin or dev)...
The real problem is trust ! No law can protect internet steals ! Chris just have to continue to register the domain name, give server passwords to 3 people not all to one child without backup good sense, and ask for private donation, that cost to him only one hour per year... I am not an expert but 30$ per years seems enough, they are some offer at illimited bandwidth and 10Go, else a real server at 30$ but per month for upload account and other with huge space.
Foundation or not, Tank will start the easy alternative if he share password to trusted person ( not necessary important person )
So, at me eye and at this moment: (3 needed foundaters with around same mindset during X years, sorry but real association and registered foundation are very annoying about vote, huge papers and other bother things...)
-Lexikos, as developer
-Fincs, a lot of thing
-Tank, first step
add to this Skan, tidbit, et caetera,.. all chairs that you want
I don't speak about all superb admin we have, but pyramid is needed.
PS: you can't imagine my desillusion, I was for Poly one years ago... try and fail...
