This is how the watches work: Everybody does it at least once. When your character is on the watch you get two to three posts then you get someone else do it. Now, when your character is sleeping you don't have to post much, maybe just explaining where she/he is sleeping or if you want something to happen. But, if your character is still awake while others on their watch then you can post normally. Once, everyone has done there turn then our characters can go to bed and then we will start the next day.
