What exactly is a cap?

Looks like link (Dave's answer) is all we know. I guess we'll have to wait and see. 表示する up on クリスマス and get one? *shrugs*

Apparently it's something あなた get if あなた visit the site on a "special" day, maybe like Xmas 日 または something I don't know but I think that's what it is. :)

I have no idea, it says I have one too. The profiles look different now, I miss the old ones. T_T

I don't know exactly,But i will wait for the first special day,And will see. Yeah that's it! :/

It's for special occasions and achievements I think. I randomly got a 秒 one a 分 または two 前 after changing my icon. :)

Well they are making ファンポップ もっと見る addictive n i have a fanpup cap....since i joined wooohoo im alredy super addicted

Well since its close to a holiday over hear its almost valentines day. So my guess is that if あなた come hear on a certain または special 日 または even a holiday such as Christmas, Saint Patrick's Day, etc... または maby even on a ランダム 日 who knows?

It's like a lid. Usually for a bottle.
