And lastly, this one is more for admins of other instances but we have opened a "LW Defense HQ" room which we want to use in our ongoing fight against spammers: https://matrix.to/#/#defense:lemmy.world
Come join us!
EDIT: Madlad @ruud@lemmy.world was easily convinced to set up a lemmy.world matrix server. So I edited the links to the new space and rooms. The old ones still work too!
I'm set up using Beeper for consolidation of a lot of my messaging platforms, and they support Matrix. That said, I'm not having any success in finding the listed spaces from the urls in the original post. Is there some kind of federation that needs to take place for this to be possible or, I dunno, is there some extension of Matrix that needs to be supported by Beeper for this to work?
Beeper can be quirky when it comes to joining Matrix channels and it doesn't support Matrix Spaces. You'll have to join the individual channels via the desktop Beeper app.
