it's ok. the post just comes up in the "new posts" section, so there's really no need to post it in multiple places, as i would guess 99% of the readers/responders are the same.
perhaps the reason that there's no equivilant here is that hong kong seems to have an adverse reaction to anything previously "used". you often find perfectly good furniture left on the side of the road, for example. my parents-in-law would totally freak out if they knew that 90% of my daughter's clothes were "previously-loved".
