What is role play?
It is essentially, a writing game. I'll spin it for you quick:
First off, you go to the forum and create a thread. And in that thread, you create a story. A world, you might say. And in that world, you create a character. When you post, you role play as your character. Now that you've made the first post as your chosen character, you wait. If other people are attracted by your story in which they can role play in, they will post as their chosen character. And once you have about 3-5 people who's joined the role play, you've created your own living story. Congrats to you!
Now that being said, don't you wanna test it out? Go for it, nothing will hurt... not even a little prick...
