So i've wandered into this place, and I'm loving it. I've played games like this on an old game forum i used to be on, but I have one glaring problem.

I don't know how to fill out a character sheet.

On my old forums, you needed name, age, race, personality, and BIO.
How do i figure out what to put into values like this? Is there an easy way to explain it?

Well for starters I'd ask the GM of the game you are playing for help OR to assign you a veteran player to assist you. I've done that in my games and the vet keeps the GM workload down.

There are many games and many rule sets here. So what system will affect the answer.

It looks like a D+D or derivative game system like Pathfinder.

In those there are several ways of getting your attributes: random rolls, point buy with X points or assigned values.

so... that is back to needing more info about your game, such as the GM or a vet might assist you with.
