I tried let it go because it doesn't really make a difference and it seems important to you and @skullbabe that it's a private foundation. So I really was going to let it drop. But you keep on saying it does things because it's a private foundation and it isnt. It's a public charity.
I've attached the letter that you said was a fake for reference. I don't think it is but it doesn't really matter.
I've also attached a copy of the first page of Archewells 990 form. If you look under the title of "Return of Organization exempt from Income Tax", you'll see a subheading saying, "under section 501c, 527 or 4947 (a)(1) of the IRC (except for private foundations)".
I might have misunderstood what that meant but if you go to page 14, also below, it says: reason for public charity status.
And if you go down to no 7, it says:
An organisation that normally receives a substantial part of its support from a government unit or from the general public described in section 170 (b)(1)(A)(vi).
If you refer back to the so called 'faked' letter, all these codings tie in with that letter.
I've also attached a blank 990 form for a Private Foundation and it looks quite different.
So I really do think it us a public charity.
