Beta builds, are they available

Brian's Mail list account

I have alpha updating. I have rc1 of 2019.2.1, and a beta build and some test builds and the stable, but beta is not updating, i see beta updates in the mail list and wondered if these are public available and if so why my beta is not updating to them.
could be my end which is why I ask.

Also can somebody remind me of how, on github to make it so I see my own posts and tickets in the email lists again? I thought I had fixed this but its gone back to hidden and I've forgotten how to allow them after all this time!!
