D: Oh fiiine.
Well. You read the Starter package thing, yes? Let's say you start with 300 Mizas. And, you need something to wear, because the SP clothes are just plain ugly. So you spend 5 gold mizas on a dashing new dress. (:P) You write
~ Dashing new dress in the equipment part,
and
~ -5 gold mizas for Dashing new dress in the Ledger section.
It was an example, but that's kind of how it goes.
For training and skills, you can get ..was it 5o, or something points from the SP. You pick a few skills your character could be good in, and give away those 50 points.
Now, when you RP in a tread, and the tread is finished. You ask a mod to look over it and gives his, or her points to the characters in the tread. SO, if you had a fight with a bear in your tread, and manage to win, you'd probably get some points to Wilderness survival, and close combat.
Again, just examples, but....It works for every skill. Dancing, cooking, or stabbing people with a toothpick. The more time you do those things, more skills you'll get, and in the end...You'll be better at it.
