I'm not quite sure yet if just anyone can go but in any case I was planning on prehosting a visit/intro to the platform next Saturday around this time for those interested. We'll try to reserve seats for the coming conference while we're there.
It's features primarily lecture based content with a few interactable worlds. Aside from that it's your standard metaverse-lite platform with about what you'd expect, 3 point tracking, locomotion, avatars, etc. The content that is there seems to be of decent quality at least and put together by actual professors/TA's from various universities. 
I think we'll screw around for a bit and watch a few lectures on whatever the group decides. They have everything from interplanetary physics to jungle cat ecology.
