Reply To: Should every kollel guy be called Rabbi or Mr.?

You should follow the local practice as this is merely a form of derekh eretz, not halacha). Remember that the last real smicha was almost 20 centuries ago, but Ashkenazi frequently use “Rabbi” as a courtesy title (similar to “Mister” which indicate a rank well above mere peasant, or the French “monsieur” which indicated a nobleman). Indeed, in Yiddish, “Reb ….. ” was the only form of address Jews used for each other (unless they person was really assimilated in which case they were “Herr” or “Mister” depending on country – which was an insult when used for a Yid).
