Anyone who wants to know about what Ryo is for, here it is!
Ryo is the money that is used in the Naruto Series, so you will as well be keeping ryo. Each member starts out with 3,000 ryo (IF they post in the hello and goodbye section).
The purpose of Ryo is so that you can learn new jutsu and gain more weapons and other cool things.
You also take away 5 ryo every time you MAKE a topic (Not reply) in Ichiraku Ramen or the Dongo shop. Reason being--you went there to buy ramen and dongos. Money taken away. The forum automatically takes ryo from you when you make a topic in those areas.
The way to earn ryo is by doing missions and making topics and ADVERTISING. Depending on the rank of the mission, you get so many ryo. And then that means you can earn more jutsu or gain more weapons! There will be more information about this in the shop area.
