Since it seems the following draft - despite based on his initial version of it and just cleaned up and reworded - is not acceptable for Nikolaus to send out to "his customers" (== donors), I post it here to let you know and discuss.
Please note that for all I know you already could follow the instructions in this letter, originally put there by Nikolaus. When you do and succeed, then please report here to encourage others to do same.
Which is something my lawyers forbid me to do, see rationale in #70.
