Email
Answering your mail.
Before you send your mail, one remark: I'm married, have two boys, a lot of work and some other time-consuming activities. This leaves me with not much time for myself :( Writing/answering a mail, certainly if it is not your native language, is very time consuming. So it can take some time before you get an answer. You also must expect telegram-style answers.
Tip for those who live in the Netherlands: add your phone number.
I've been SPAMmed several times in the past so I give you my address in encrypted form:
Replace " at " with the well known symbol and replace every "x" with a dot.
The first address is from my work and checked during breaks. The second one is my private one but only checked a few times a week.
