One of the ways I found good channels was looking at others subs. YouTube took that away. So I haven't been finding as many good channels of late.
I sub you back Glorfindel. In the upper right corner, there is a pull down box with your video manager, subs, settings etc. That is where your Subs are.
Two other things, one I don't get the updates on new videos the way I use to, and two. personal messages are broken. I get them all the time, and I can't respond unless I go to their channel and post a message from there.
