Can one use the term "Rebbe" in place of "Rabbi" freely, or is "Rebbe" saved for Rabbis who one has a particular liking to, or thinks highly of?

http://www.jewfaq.org/rabbi.htmRebbeRebbe is the term for the spiritual master and guide of a Chasidic community. The term is sometimes translated as "Grand Rabbi," but literally it simply means "my rabbi." A rebbe is also considered to be a tzaddik (see below). The position is usually hereditary. A rebbe has the final word over every decision in a Chasid's life.
Outside of the Chasidic community, the term "rebbe" is sometimes used simply to refer to ones own personal rabbi or any rabbi that a person has a close relationship with.
The term "rebbe" should not be confused with the term "reb," which is simply a Yiddish title of respect more or less equivalent to "Mister" in English.
