I am a pantser on short stories, sort of a plotter on longer ones, BUT, even within the plot, there's room for putting on some pants -- I generally control that to finish things, but this is also why I tend to write series of things and am a long-form writer consistently ... plots get extended and side elements get their own plots!

I also can HIGHLY recommend @freewritehouse, @mariannewest, and all the great members of the Freewriters Community -- they will nourish your inner pantser AND leave you room to develop the plotter as well: the weekend freewrite can be chosen from all the prompts of the previous week, so if you want to "plot" a weekend freewrite, you can!
