Just an update -- I haven't taken any action related to my "Adjusted" principal balance since getting Prosper's final reply through the BBB. I'm re-considering whether to even pursue this in small claims court. The outcome is not guaranteed, and even if I do win, $1600 is not really worth the time and effort, frankly (plus, I'm busy with my family, real job, life, etc.).
I may just sit back and watch how the fifth (and sixth, and seventh?) year of the class action suit unfolds.
I'll check in here every few days to see how everyone else in my "boat" is doing.
Take care,
James
