Monika,
There is no need to feel embarrassed

considering all the great help you have provided, I have no right to complain. This forum has provided so many useful pieces of advice and of course translation help. This past week or so I have been most privileged to have found such great help, especially from you. I wanted to compliment you on your English, you communicate better than most native speakers I know
Again thanks so much for your willingness to help.
Regards,
Hugh
