The idea for an online resource center came during the training course “Train the Trainers – It’s Up to Me 4” that was held in 2017 in Germany. During the past four years of conducting this training course, we have been collecting learning materials for the participants from a variety of sources – books that we have read, videos that we have seen, guides that we have developed. However, the resources we had did not meet the needs of the participants and their need for specific learning materials. Google Drive materials which were collected for several years in the form of scattered materials here and there were obviously indicative of the need for a more structured and well-organized resource center from which trainers could develop their skills and competencies.
