Like others said, you "become" your character (or fursona,
if you want to be yourself) and it's typically like a "live"
story.

If your on the RP box, you can Roleplay
like this:

*(Your character) walked by the
river, sat down, and smiled. S/he looked at the river* and
so on.

However, on the forums, it's different.
No asterics (*'s) and typically it has to be 3-4 sentences
(unless it is said to use more, stated by the starting
post)

Also, when your character is talking,
it's typical to use quotation marks (")

Example: "Hello!"

It can get very fun :D

I hope that helped

Good explination Cobalt & Tani. That is right.

You 'become' your character, and type a story with others by
saying what your character would say or do. Hope that
helped.

What they said or for short and simple: you create a
charicter and make a story with the charicter then people
follow along with the story with their charicters. (Ok. So
it wasn't short but it was simple am I right?)

pretty much what silver said..

Person A- *Shard
smiles and says,* hey im sorry. i was mad
Person
B-*Dragon glares at Shard and then starts laughing
ect
(sorry for continues silver i had to)

its like you have a charectar and yo tell it what to do,but
only you controll your charectar and no-one elses
EG-
Person A-*Shard takes a stone and fires it*
Person B-*Dragon gets git by the stone and falls "Ow" he
mumbles
ect
