mine comes form when i first played Runescape. It was my first mmo where i had to have a name. i was with my older brother and he said "why not name yourself youto000?" and i said sure. it stuck with me so now for every account i call myself youto000 (or 176 if 000 is not available). so that is my story.
i think it would be cool that you have reward weeks like on holidays or weekends you have double rewards for a specific amount of time like C.O.D. and Runescape
