Towards left side of the screen, click that button.
You'll get a pop-up with that o-so-recognizable Facebook Like thumbsup. Click the blue button beneath it to proceed.
The next page you get are two fields for you to fill up. Top box is for your desired username for the beta account you will be creating. Second box is of course the password for said account. They did ask you to remember these account details as there might be prizes in OB where you redeem by submitting these account details. Once you're done, click the blue button near the bottom of that screen again to proceed.
This is basically how you can redeem an activation. You won't be getting any keys, the account you create there will be solely available for betatesting Fantasy Frontier. The activation period only starts from 8PM taiwan time everyday until the 11th. (7/4(四) ~7/11(四)，每晚8:00 which means July 4 to July 11, every night at 8PM).
I only managed to get my activation on the second day where I spammed enters on the button. You MIGHT be getting some popup error messages that tells you that "has been activated", "all activations gone" and stuff like that if you run the popup messages through google translate. Nothing to worry about, it's kinda their default message telling you that you're unsuccessful, so keep spamming the enter button away until you get a page where it tells you you're successful if you run the words through google translate.

Hello! I really want to play this game. My Questions:
1. when will close beta ends?
2. In registration, does it requires info such as those being asked in korean websites?
3. Is there IP Block?
4. In short, even if I'm not from Taiwan, I can absolutely play the game right?
