Aiya Daniel, you're a brilliant guy. I am sure you will know what I mean by 'engage' if you ponder on it for 5 seconds. It's like...how to say..hmmm ok think lah..its like the PM, perm sec or a celebrity replying in forums to people- all who don't know them in person- talking about them lah. I'm not saying that you're equal in stature to the PM (for now). But can you see the same concept applies here? It never happens. And is very odd lah. You're the first and there's been more than 200 PS already. Its very strange that you engage, that is if you're not an imposter. Which I still think you could be =P
