1)RPG Characther Plots This is an individual plot for each characther, it's a storyline that you want to follow or make for your characther.
2)RPG Seasonal Plots If you wish to make a season plot write out a story for the characthers to follow then pm the members that you want them to participate in the plot you made finally, write it out.
For example: In the charmed rpg I want to make a Season so I call it
