If you feel generous and you want to support me and my work, please check my Patreon page:
You can become my patron and in return you get to see future pictures in progress way before they hit the internet, make suggestions on what I should draw next and other cool stuff X3
It's in construction for now but I'll also be present on subscribestar soon: https://subscribestar.adult/karbo
I do not mean to be presumptuous however I was able to join the Felarya group and post a couple stories with relative ease. It was quick and quite simple. And I believe that as long as you provide a list of the creator and the group while acknowledging the stories origins it should be fine to post stories.
(Of course I am relatively new to this sort of thing, I have only done two stories so far, If any admins read this feel free to correct me.)
