Hey Yana, there are two aspects to the partnership I guess. As far as the ability to earn by asking questions, Yes, it's invite only (though I have no idea how or why they invited me). But as you might have heard, anyone can now opt to have your answers put behind a paywall, similar to the way Medium works, and people who pay can read your answers. You can also earn money this way, if someone who posts questions (like me) makes a "request" for you to answer specific questions. :-)
