You see, this happens with every single update. We need to make sure everything is working properly. It is currently donators only and will become fully public at 7:00 PM EST tomorrow.
If we made the server public right away, it could cause certain issues. For example, if a duplication bug was found, the server would be roll'dback accordingly. It is easier to rollback a server for 100 people rather than 400 people.
Sorry for the inconvenience, it is just normal protocol.
We will not be dealing with raging/ complaining.
