Hi!
My brother participates in this group in his hometown in the USA. It's a way to meet up with other people, who would like to meet others outside their current social circle. Not for business - just to have fun (and not meant to be a pick-up scene either).
The powers that be at MEETIn just created a Hong Kong group. Check it out. Let's get this thing going!
