Best part for me is the new stuff. Today that dendrite + bridges script looks promising. Too bad I always run a dendrite server, maybe I can start over some points later in the guide.

Another solution comes to my mind. Why not using freshrss or alternatives and achieve sub’s through RSS?

Didn’t look into it further, the project is new, maybe they add this as a feature if requested.
