(its okay. so basicly how this works, is the categories that are labeled as places (beach, farmhouse, forest, etc.) are places you can post your own rp thread or join in with another.
this basicly meaning that the thread you post is still featuring your character, and has the same plot that the entire forum roleplay is set on.
so if you were to post your own rp thread with your character you would choose the place they are at (this meaning any of the boards clearly labeled as a place (ex: forest, farmhouse, mountains, beach, etc.) then you would post a new thread and label it whatever you wish. something involving the small conflict your character is facing. then you would post ur rp starter.
example (this is just my rp thread i posted on the forum earlier)
board: beach
thread name: echo is just wandering
rp within the thread (this isnt the actual rp writing i posted):
echo trotted about, eating food that she saw. She saw a racoon in the distance and chased it off into the ocean. she trotted off happily, feeling victorious
keep in mind that when ur really rping, be descriptive. whats on your chars mind? what are they doing? what time of day is it? whats the weather like?
if your replying to one and rping with them, well your basicly just replying.
hope this clears things up
