Trying to keep this thing alive...
While a tragedy befell the once beloved NaNoWriMo--there is nothing stopping NaNoManGo from carving its own way. What it needs, however, is word of mouth and community.
I've built this BlueSky feed. All you'd have to do to have your posts seen is to include NaNoManGo somewhere in your posts.
I also have this Tumblr account that I've flipped for the sake of NaNoManGo where I will try (try, try!) to re-blog everyone who participates in NaNoManGo. I won't do this until December though.
If you have any community resources for other socials please post them here (like a NaNoManGo discord?)
