I got full permission of copyright usage under GFDL conditions.

wording (personal names deleted of the email conversation) of the correspondence concerning copyright: ulsuud@yahoo.com wrote Dear .....;

  To the principal question that u have made me, my answer is: " Yes, I
  agree the prerequisites you have asked me", so, you can see my
  thoughts, I believe and support  the free exchange of files in the
  net and I've not any problem with  my copyright, so please, notice to
  the wiki resp. that you have all my permission to upload my files, even
  for commercial purposes. 
 I wish u this will be sufficient to made your work.
 Greetings again;
 Mr. .........

My email content was: Dear ....

thank you for your positive answer. The problem with uploading your flags and coats of arms in wikipedia still is, that wikipedia, resp. wiki commons wants a largely unrestricted copyright, because the principle of wikipedia is, that it is "open source" content (presumably to avoid lots of litigation that endangers the project). This also includes use for commercial purposes which you restricted in the text on your website. The habit (GNU-liscense) on Wiki Commons is, that it is free also for commercial use provided that the name of the original author is named. Wiki Commons is quite strict on these question so I have to ask you again: would you also agree to this prerequisites?

Greetings, ....
