TERA Europe beta test? You're in luck because Frogster is hosting one later today (at 2:00 p.m. EST, to be exact). The Velika server is being stress-tested, and Frogster is raising the player cap in order to see what happens when large numbers of people attempt to log in at once.
TERA Europe community manager Raven says that "you might experience lag or other issues" and that "this test is not intended to offer you a normal gameplay experience." If you're OK with that -- and you feel like volunteering your time -- head to the official forums to learn more (and set your alarms accordingly).
If you're wondering about TERA's American client, En Masse Entertainment sent word that last night's pre-test dress rehearsal "went swimmingly."
