How is it when it comes to other Fediverse software?
* a.gup.pe is known to only 100% working with Mastodon-powered instances.
* Lemmy, Kbin, Mbin instances are hit-and-miss with the rest of the Fediverse.
So far, the only ones that works consistently with any Fediverse software are the groups feature of Friendica (and Hubzilla).
In addition, there is also fedigroups.social which works with any Fediverse software.
The Newsmast Groups software works well with the rest of the Fediverse? I mean, not just Mastodon-powered servers, like Friendica and fedigroups.social ?
