I was recently on a Lubavitch dating site in which the following profile question was asked:
Hiskashrus (select all that apply): __ 770 __ Igros __ Ohel
Is this question asking how you prefer to get advice from the Rebbe? I guess "770" would be going to the original shul (the one that is now Meshichist [?]); "Igros" would be seeking answers by opening to ~random pages in the Igros Kodesh; and "Ohel" would be visiting the ohel and maybe leaving kvitlach.
Is this correct?
Is there anything else involved in "770," for example?
What are the implications (re: Chabad subgroup, etc.) of each option?
