@manton It's indie powerful, and maybe that's why it is confusing. The first time I clicked on that page, I didn't understand its relation to the cross-posting feature. And although I now get it, I think that page should be split into two: cross-posting and feeds. Instead of having the list of cross-posting accounts there, it would be just the blogs RSS feeds.
And talking about the feed, it is not intuitive to have to manually add other Mb feeds there.
Related to that, making the cross-posting options linked to having the blog feed added to that page is sometimes a bad idea. I had to remove one of my blog's RSS because it was in Portuguese and that was making a mess in my main feed that is in English. But now, there's no way to automatically share that blog posts on other social media.
