The easiest (and the most reliable) way to contact me is through the comment section below. All comments are moderated and will not be visible to anyone except me, so feel free to leave all the questions there. Don’t forget to put the valid e-mail address so I can reply.
If someone prefers more old fashioned communication channels like for example an e-mail, it’s also possible: rewolf [at] rewolf.pl. In general, I try to answer within a week, sometimes it can take few weeks. Do not hesitate contacting me again if I left something unanswered.
