Here's how to join, taken directly from his blog:
HOW TO JOIN
1. Open only to gamers residing in the Philippines (PW Philippines CBT is locked to our country, sorry)
2. If you already won at the first contest or at Waukster.com, then you are ineligible. Period.
3. Second, like before, to join the contest, you MUST *subscribe* to my blog via my Feedburner e-mail applet on my right sidebar. Be sure to *activate* your subscription. Inactive subscribers cannot win.
4. Now, it’s time to be creative. Instead of just simple questions, I’ll be throwing pretty hard “complete-me” phrases (or some equally “evil” brain teases). This will be posted everyday.
5. There will be three (3) winners everyday until the PW Closed Beta on March 28, 2007. Winners will be announced here regularly.
6. Instead of submitting to my email, you have to submit your answers to email@example.com, the PW Team will randomly select the most creative answers and inform me ASAP. Before, it was submitting fast and being first… now, even if you’re late but you have a cool answer, you still have a chance of winning.
DON’T FORGET TO INCLUDE THE FOLLOWING INFORMATION in your e-mail
Complete Address (with zip code preferably)
MylevelUp or Netgames username (if you have one. Either will do)
Blog URL (if you have one):
Your email subject must be (GMTO PW CBT 2 – for )
Instructions on how to claim your prizes are here.
7. But wait! There’s more! If you have a blog and include my blog (http://gmtristan.blogspot.com) and Perfect World Philippines (http://www.levelupgames.ph/perfectworld) in your blog roll, (and you replicate this contest on one of your posts) then you get NOT ONE… BUT TWO (2) CBT accounts! Woot!
