How I wish I could, but there's no registration page or something to become a member, but instead you need some kind of referral in order to join on that forum.. nah i feel like that forum wants to be important... and i hate going trough it. Its like begging to be a member... if they really love jpop song like their forum name "jpopsuki" they should welcome people who loves jpop songs too.
Like Scandal-Heaven, Jpopasia, Ikimono.forumotion, jphip.com and etc... Anyway it was just my oppinion.. every people have different thought so cant blame them i guess..
