I see that beta release is planned for July 2018.Do you plan some kind of giveaway for most active participants?
Do you know if it will be open beta?
Maybe they will start with closed one,but at one point they should make it opened,so more people can test it out
I think it's better to start it with closed group, and once it's more polished, then you open it for everyone
I think they still have internal testing, that's not a problem, and open beta would come after that, so I wouldn't mix those two.
