PeerTube instance with good reach?
@FediVideo Hi, FediVideo. First, thanks much for all that you (and your alter egos) do here in the Fediverse! You are a treasure. 
I am wondering if you can recommend a PeerTube instance with good reach that I can join? My goal is simply to have an account that I can log into on the raspberry pi connected to my TV to view, subscribe to, and maybe occasionally leave comments on PeerTube videos. I have no need or desire to upload videos.
A couple of weeks ago I visited your website, and subscribed to the PeerTube server that you were suggesting that day. It works just fine for the videos hosted on that instance, but of all the channels that I have searched for there (several of which were your recommendations), only one was found. I can find all of them on your instance, but since you don’t allow signups, I cannot subscribe to anything there.
I would be very grateful if you could recommend an instance that has the kind of reach that yours has, and allows signups.
