I post chapter bundles on NG, but also on:

Tapas:

Itch io:

https://vanveleca.itch.io/

Tumblr:

https://rockerellameetsmerman.tumblr.com/

And...I think that's it so far.

I've been think of making posting it to Comicfury someday, but idk how many people still use that site. If any of you use it, how have your experiences with the site been?
