I am truly sorry, but currently (April 5th, 2018) my contact page is not working anymore.
And I do not know when it stopped working.
It will be back online as soon as the change (in its environment) causing the problem is found and remedied.
In the mean time also a statement will be drafted with respect to the European General Data Protection Regulation (GDPR). ( http://eur-lex.europa.eu/eli/reg/2016/679/oj)
