Allstar is a portal I meant to cover before, but I seem to have forgotten to write about it. I found some old sign-up photos stored away in my blog photo directory but they're out of date now. Allstar has changed their sign-up page a little since I took those screen captures. However, signing up for this site is pretty straight forward and easy. Head over to the site and have your i-Pin ID ready.
Start by clicking "회원가입" underneath the red login button. Ignore the impulse to use the foreigner sign-up form. If you do this, your account takes time to be verified. They expect you to fax or attach a scan of your passport for verification. Using the i-Pin you can pass on your details to the site through the normal registration process. So choose the left-most option. Then click the i-Pin tab on the next page and launch the i-Pin interface. Sign-in and it will pass on your details to the website. Fill out the rest of the form and away you go. The form has all the standard questions. I can't recall right now if the ID and nickname can be the same or not. Their captcha has changed. You don't write what you see, you might have to do a math question. So basically put in the value of what you would get. For example the current captcha on the foreigner registration page that I can see says "8+4+5" so I'd enter 17, not "8+4+5".
The reason I bring up this portal is of course a first person shooter by the name of "Another Day". I played this game last year during one of the beta tests, but it didn't run that well. I tried it briefly a few months ago again and it was much better. Now with the new machine I'm going to give it a proper go and write it up.
