[k3b]

Acording to https://forum.f-droid.org/t/known-repositories/721 and https://s3.amazonaws.com/storymaker/index.html there is a public fdroid compatible fdroid repository at

 https://s3.amazonaws.com/storymaker/fdroid/repo

when trying reading from it i get error message "AccessDenied"

trying to open

https://storymaker.org/

gives me a timeout

does the project still exist somewhere?
