Effective with version 1.0, Everyone that has gotten an invite into Home are considered 'stress testers' and as such do not receive the HBT rank. The HBT rank was mainly so that earlier in the closed beta they could report bugs and discuss the inner workings of Home without risk of breaking the NDA. However, since the open beta will be here soon the beta boards are going to be closing soon; the HBT rank will be dissolved when Home goes to open beta most likely.
thanks for the in-depth answer. Preciate it man. Well atleast I have it and got a invite.
