There are two ways to communicate with me about mental models. First, is giving comments into the blog posts. Second, is through email. The address is firstname.lastname@example.org. Be patient if you are not getting the answer soon.
Finnish is my mother tongue, so do not be surprised if I have to ask what you mean. This shouldn´t normally happen, but sometimes it may be the case. I hope everybody´s comments about the blog are in English. You can try to ask questions through email with English, Finnish, Swedish, German, and Spanish. Swedish, German, and Spanish are the weakest languages, but I will probably understand what you are writing. I may have to answer in English in those cases.
