Hi,
I just received an e-mail from the editors of kormany.hu that they recognised the fault and contacting the responsibles who will contact us. Hopefully it'll be a positive answer.
In my Hungarian letters i completed a little bit the model letter from the FSFE page and add the list (2 :)) of institutions who have already corrected their websites. This is a good example how to change their own pages and motivation to do it.
I also tried to add some hints that they are official institutions and maybe they should pay more attention to these kind of details.(very politely of course)
Regards, Eszter
