I've changed my/developed a schedule for all of my The Outsiders fanfics;
No Good - Every Monday
Brothers Friend - Every Wednesday
Pearly Whites and Cigarette Buds - Every Thursday (starting next week - might publish a part before then)
Back to The Past (my upcoming Sodapop one) - once published, every Friday
Of course, this may not be 100%, just a hopefully consistent thing that may align with my actual schedule and give me motivation/time to think of more part ideas.
