User:Proofname123

38 years old. born september 1981 september 17. My name is Dirk-Anton Broersen and I live in Didam, near my hometown Zevenaar. I work in Doetinchem 15 kilometers (10 miles) nearby where I live. I'd like to add my knowledge to proofwiki, so it can be discussed, or look for others who have posted on interresting subjects.

With friendly regards,
