@simsa04 @lohang From the things I've been reading about groups in GS v3, devs have been contacting with other #fediverse software projects just to be sure there will be compatibility.
Also, I know Mastodon is said to implement groups in the future (I think more because popular demand than for devs willing to create them), but if #fediverse history has made something very clear is that Mastodon and GS groups will not be compatible. I'd love to be proven wrong in the future.
