If there are still problems you should open a new issue. We cant leave issues open forever because they go stale and dont account for new features. By the way we are planning to implement multi-communities.
I’m surprised that there are still instances out there running 0.18.2-rc2 or 0.17.0. Those versions are full of bugs and miss so many features.
You can get the raw article text from fandom by clicking the edit button. Then you need to convert it from wikitext to markdown, there are various tools for that. Finally post it on Ibis. Fandom also has an API, so you could write a script to automate all this.
