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.
