Izzy, I understand your attempt to assimilate with the native Dutch speakers, but we have a policy that if possible, foreign posters should be adressed in the language they use. The problem with Google Translate is that it sometimes has a lively imagination that can cause some misunderstandings.
If you contacted the inactive member, it is possible that he had at the time activated the option to be notified of any private messages on the forum. Then it's just a question of when he opens his mail box. Sometimes ship builders are known to post with large intervals, even years. But keep in mind that the heydays of shipbuilding on our forum have a bit waned, though you should be able still to find people here who can help you with this question. Some more specialised shipbuilding fora exist, like
http://www.modelbouwforum.nl/, that have multiple updates per day. I hope you find the right info.
