I have just received up-to-date contact information from Ronnie Wouters in Belgium, and it includes a link to their blog: http://blog.seniorennet.be/knopenlegger/ which has some excellent photographs.
If anyone knows of a translator for this site (Babel didn’t recognise the Belgian language) I would appreciate knowing of it too.
If you want to just translate text then MS Word gives you access to Microsoft’s online translation (copy and paste from the website) - it’s again understandable if sometimes quaint.
