Self-directed learning or even more exactly management of self-directed learning is one of the basic skills in the contemporary world for everybody and especially for adult educators. They need these skills for at least two reasons. First, the adult educators, especially those who are working in non-formal education, are very diverse and have very different possibilities to develop their qualification. Because of this the electronic platform for adult learning in Europe (EPALE) was established. Such knowledge systems, such platforms are very useful virtual learning environments for all adults. They create a lot of opportunities for users but at the same time raise some challenges and problems also, because to use it qualitatively adult educators need some skills and attitudes. For example, the exceptional feature of this platform is that active users can not only use the information, but also create or reconstruct, in other words, manage, the content of the platform also. It offers a place to meet and discuss important adult learning topics, as well as to exchange ideas and materials to support professional practice. This type of community platform is the first of its kind for the sector of adult learning, especially non-formal, but to use all the possibilities of this platform it is necessary to be active and able to manage your own learning process, in other words, the learner needs skills to manage self-directed learning. So one of the most important skills here is skills of self-directed learning and management of such learning. Moreover, the second reason is the need to be able to develop these skills for their students. Nevertheless, at first adult educators should have these skills by themselves.
