The original has become a caricature of a board now (Expat Singapore)
Singapore Forum was originall spun off due to a falling out between the owner of that site and Expat Singapore. Has it's own character now. (love it or hate it)
This board (#3) Seems to have been set up using the same business model more or less (Real Estate is the sites primary purpose - High End Expats primarily $300K or more

)
And the newest pretender to the thrown (sic!) ExpatSingapore Proboard105. Again, formed due to a disgruntled former member of the original. Unfortunately that one is going to go the same way as the original as it is full of flamers & baiters (unregistered ones) always slagging off one another.
Somehow that sounds like this board as well - except it's the regulars who do it!
Course there are the local oriented forums as well but we'll not mentioned those.
