Smartsig is a License(like the 1 in my signature) that can be made for either Super Smash Bros or Mario Kart Wii. They Contain your favorite character, favorite track, your Friendcode and your Mii name. The background of your Card changes according to your level. There are 2 ways to Level up, either by someone clicking on it and leveling up (max 1 level per license) or using promotion codes(promo codes). You get Promotion Codes after you level up a certain amount of other people's licenses. Promo Codes vary in number of levels you gain. A hidden trick to gain extra is by entering your Promo Codes into the Promo Roulette. After you put it in the Roulette enter it in the update license section and you'll have gained 1 extra level. One more thing, You can only make 1 License per game per License meaning your Sig can only have 1 Mario Kart License and 1 Brawl License.
