Characters Under 4 weeks are not allowed to fly with WTM. FCs may make an exception and invite one if the pilot is A, in an optimal hull and B, can prove that they have some experience playing EVE in general. FCs at no time are required to invite these characters until after 4 weeks in game. This info was in the MOTD for about a month as general news.
This policy is to prevent abuse of our upgrade policy with the ease of rolling day one alpha accounts, also to give true newbros time to actually learn basic in game mechanics and to train some skills.
