If you want to contact me, it is best to do so via the email address of this website. You can also add attachments such photos, for example if you have a question about a symbol. But also emails with friendly messages are always welcome. If you have discovered a spelling error or a mistake, I would also like to hear about it, I always try to improve the quality of this website. Junk emails such as unwanted offers, phishing messages and other attempts to scams etc. will be removed by a strict spam filter. So always make sure to use a good subject text and enough text in the message to not be marked as spam. It is nevertheless possible that your message ends up in the spam box, this can occasionally happen by accident. Regards, Hein Pragt.
