From Collive today: (This is a MAINSTREAM normal chabad website – not meshichist:)
Shabbos Night Live with Rabbi Shmuel Butman – special broadcast for Gimmel Tammuz: The Rebbe himself will find a way to answer your questions and give you his guidance and the special mission he gave each one of us.
They believe the Rebbe has koach in this world – pure avoda zara (yiddishkeit believes tzadikim can intercede in shamayim, chabad believes the Rebbe controls both worlds.)
