Every single year LCN promotes an annual conference, where the members have the opportunity to meet each other in only one business trip. In order to benefit the partners from all continents, LCN will organise its conferences in a different country and continent a year. In addition to that, the conference period will be always the same, during the first semester of the year. In this way, everybody is able to guarantee his participation in advance.
As one of the main rules, it will not be allowed to be absent from more than two consecutive conferences. You may be right that the conferences represent more an investment than a real cost.
