How do i get access the guix class/forum thing that David mentioned?

I signed up for a system crafters subscriptio/membership, so i could get early access to some guix related system crafters stuff, and i have no idea how to actually get access to it.

Can you see courses under Categories - System Crafters?

Yes:

Is that it? Does he post things there first and because i have access to “courses” i can see it?

Maybe there’s more but as I only got the Guile course I don’t know about others.
