right now there is no way to change your host (Mastodon domain) in App Configuration.
I run WriteFreely on my Yunohost server.
When I first started, I had a blog.arkadi.nohost.me domain, but recently changed to my own domain.tld -> blog.arkadi.one
It seems federation is first setup automatically but there is no way to change it later. this should be changed I think because federation with activity pub is one of the killer features of WriteFreely in my opinion.
*** Seems like the only way to change this is for me to uninstall WriteFreely and then reinstall it again. This is another major problem because I can export posts as a ZIP file but cannot re-import them.
Is there a way to change it manually in a *.conf file or something?
