Contrary to some reports that Joost has gone live with unlimited invites and 150 channels – at least that is not what I am seeing. I don't know if I need to do anything "special", but here is what I have when I login to Joost.
Number of Invites: Zero, yes that is a 0 as in nada, zip, zilch, etc.
Number of Channels (so far): 26 – not 150, but 124 less.
