Well, NaNois very much not about getting top quality stuff out--its goal is just to get people writing, period, since so many of us always want to write novels but put it off, make excuses, don't have time, edit too much too soon, etc.
Regardless, I'm glad to hear FW has been good for you! That's awesome.

And good luck with the fanfic writing, too!
You can definitely do better. Never doubt that!
