For all of you who have been mailing me asking for a post in English today, here's the translation. I will keep in mind that the majority of readers is no longer 'local', so sorry about that and I will do better in the future.
From my archive I rooted out a picture and scanned it. (see previous post) It is a smaller version of a big poster (A1-size) made by Wim Thijs and published in 1989 by the KNWV (our MNA). For years I've been looking for this poster. If there's a reader who still has a copy and doesn't mind parting with it, I would appreciate to hear about it. We can alway negotiate a fair price.
The rule numbers are no longer in use. I'm thinking about making a new updated version.
How many of you were able to get the gist of the post just from the Dutch version?
