storage requirements are a serious issue for large public Matrix servers

Should I still consider joining tchncs then? I don’t really want to overload their servers. I’m only in a few rooms with little activity, though.

Is a Docker volume accessible like a folder if I SSH/SFTP into the host machine, not the container?

Don’t put any data into the container ever. All of your data and configuration should be done in volumes. So are bind mounts (–bind) to the filesystem bad? Am I able to access Docker volumes through SFTP/SSH?

I live in Canada and screen recording a phone call with audio doesn’t work, and the option that seems to be in the phone app for India isn’t on my phone, even though Canada is a one-person call recording policy country.
