MindMatics brings us Knights of Prosperity - 94444

I texted 'join1' to 94444 as the press release directed me. Nothing happened. Here is apparently what should happen according to http://www.mindmatics.com/en/01/content-03-1.html?id=1&year=2007

They mention another program with Maury: http://www.mindmatics.com/en/01/content-03-1.html?id=2&year=2007 but there were no instructions in the press release.
