@P.F.KERR: I was aware with some problems about that but not that it was totally out of function now. An alternative posibility now is maybe a personal message to the member / poster, using the mail-facility of this website?

I'm sorry to say Pieter that the error reporting tool hasn't been working for the last couple of months. Believe me, I've tried many a time.
I don't know of any other way to report them.
Regards.
Peter Kerr

@Paul Gowen: errors can be reported in a special section: under each photo there is:
"if you want to report errors - CLICK HERE instead of posting a comment!"

Dear Sir.

You have got this tug not in the right Categerie it has to go into Tugs.

Regards
Paul.
