It's too early to talk about how we will invite people to the game - I don't know how many people we will need initially, it depends on early perfomance of the game and how many testers we will need. What is for sure - people who donated will be invited first. Other than that there could be various criteria to invite people - those who were active on forums, veteran players from our other online game GUNROX (when we will need young male players to test how our typical Totem Tribe audience will stand against typical MMO kids) and so on.
