My thoughts:
This is an APRIL FOOLS JOKE. Why? Let me tell you!
1) Online dance class? Hardly! Possible, but Michael wouldn't have it this way!
2) This picture looks like an e-mail that they originally got from Michael Jackson Live, but screen captured.
3) You cannot use that "browse" feature in an e-mail!!! Even if you could, the "browse" button would surely have dots after it! [Browse...]
4) VERY doubtful that you can actually submit a form through e-mail. You'd have to follow a link to get to the form you'd need to submit.
It's a clever joke, folks! If it isn't... Then.................. :woohoo:
