A post on IncGamers indicates participants in the StarCraft II beta test have been receiving additional invitations to recruit a friend in the beta for the RTS sequel. They have an additional note clarifying that opt-in beta invites are also still going out to those who have registered,. There seem to have been problems with the friend invites at first, but this has been cleared up, as they have word on a resolution: "Yes, all keys should be working now. Sorry for the inconvenience. Now go show your friends how to play StarCraft 2!"
