Kagamine Rin and Len are the second installment of the Vocaloid Character Voice Series from Yamaha, a brother and sister pair. They were released on December 27, 2007.
Their names came from the combining of characters "鏡" (Kagami/Mirror), and "音" (Ne/Sound).
That's a great idea, but inviting members would also be much helpful (faster).
Well of course, membership cards would attract more, but I do hope those who will join the club knows what Vocaloid is. >.>
Anyway, good luck with this. *thumbs up*
