FlorianHa I’ve heard that with donations you get an extra 500 MB.
Correct, by default it’s 500 MB, donating adds additional 500 MB for total of 1 GB, see https://freeflarum.com/donate
FlorianHa After how many weeks of inactivity is the forum deleted?
Inactive forums are forums existing for at least 2 months with the main admin account last seen over 60 days ago - after that, the forum is removed in the next cleanup cycle which is approx. every 6 months. This can sometimes flag forums incorrectly, in that case you can e-mail me and I’ll restore the forum for you. See https://docs.freeflarum.com/en/legal/terms/#3-fair-use-policy for more details.
FlorianHa and I got his header wich does not look reeealy good. Is there an option to remove it?
You likely put the text in Admin > Appearance > Custom header (or some extension). Removing it from there will get rid of it on the forum
