The contact gp.mpju(at)gov.si is publicly available below at http://www.minus25.gov.si/ I have sent a suggestion for improvement to them and after 13 days there is still no reply. So my suggestion is: get someone to read and reply to this mail or give a more specific mail e.g. minus25@gov.si or something similar. I like the minus25 initiative very much. Thank you and keep up the good work, Matej
