I tried, first the signup page doesn't show the form on 3 separate browsers.
Paused my adblockers, nah no luck.
I don't remember what I did exactly using dev tools but, noticed the form was there, but just not being rendered. Somehow made it work, and signed up. Never got access, even after a month.
Mojo is all talk for now.
They could've just paused the marketing until it was atleast in open-beta. Why the hype without allowing access.
