Currency ($) on the forum

I'm a newbie. I've tried to search what $ is the currency used on this forum and have had no joy. I noticed that some ads state 'S$' and others only 'S'. Re the latter, is it the US or Singapore dollar that's being referred to? Thanks.

hi bro, we are a small kampong community here ;) ...use our SGD.. never seen anyone using USD or any foreign currency as there's no need since we always do meetup sales(cash on meetup/bank transfer etc).

Yup, we are a Singapore forum, so it's definitely in SGD. :)

That's super! This is starting to look even better... Cheers.
