Hello aHeiligeYid,
I think it may have been Feif Un who began an advice column first — I just checked the initial posts in Popa’s thread, and I read Feif Un’s advice thread a while back.
However, Wisey did ask “who began an advice column,” rather than asking who began one first, so perhaps either Popa or Feif Un is the correct answer. Or, if Wisey was looking for an answer that included everyone who started an advice column, then maybe the correct answer is Popa and Feif Un (anyone else too of whom I may not be aware?).
Wisey, can you enlighten us please? 🙂
