XII International Conference on E-Commerce and E-Business – E-Commerce 2012 – has passed as well as expected. A large number of interested participants discussed the problems and challenges of e-commerce. Implementek has traditionally participated in this conference, once again in the role of a lecturer. Vanja Al-Halidi had a lecture on the topic: “Migrating of the E-commerce System / What can go wrong”. Our efforts in the education and dissemination of electronic commerce in Serbia have continued, but a statement was again repeated that without an active participation of the government and better regulations, we will not be able to have a serious breakthrough of e-commerce in our country. The beautiful ambiance of the Palic lake and good weather were once again one of the main advantages of this conference.
