En Masse has announced folks can start signing up for the closed beta of TERA. Dubbed as “preview events”, each phase requires an invitation with the end event switching over to open beta testing for all applicants. Each invitation to an “event” will inform the applicant which test it is valid for, with each invite distributed via random selection. Those who participated in the alpha phase will be granted access to all remaining tests. You can sign up for the beta through here. Thanks, MMOcrunch.
