Is there some kind of Dutch support group?
I have some issues which are hard to explain in English.
More or less to my knowledge of the English terminologies 
There are no language- or country-specific support groups. Asking on the public forum for help via private message from other Dutch members will get you the assistance you need. (If you are not familiar with forum features, private messaging is available by clicking on your avatar at the top right corner of the screen.)
Hi Martin,
As Tut wrote, there is no Dutch support group, but I am Dutch and you can send me a private message and maybe I can be of help.
Kind regards,
Hennie
