Hi Emdee,
A Hong Kong forum's a great idea... I am hoping to revisit HK next year so (speaking selfishly!) I would find it useful - plus when I'm on the ground there I can feedback up-to-date info and recommendations to the forum.

My long-term plan (5 years+ ) for this site is to slowly grow it to cover increasingly more of Asia. I originally wanted to increase activity in the existing forums before creating more new "tumbleweed" forums - but on the flipside, the earlier I create new forums, the more time they have to get established.
So I'll cook up a Hong Kong travel forum a bit later today and get my thinking cap on for a few posts to start the ball rolling!
