@ Shengjie: Why you want to know why he wants to know?
If you have and want to share the answer, share via PM if it's sensitive. No need to question him why. We're all here to share and promote vaping as a healthier alternative to smoking. If you don't share, then just read and press the next thread buttom.
For your info, and anyone with any common sense, the government don't need info from a poster to take any kind of action. By now, they would have more info that 10,000 yous.
So share with members who need help with info. I'm sure when YOU first started, you didn't know a lot of things and bros here shared with you without knowing your name, address and NRIC number.
@dayn: Like what curry bro shared with you. Read some past threads and do some googling. Getting some info on your own taste better than being fed wholesale.

On that, welcome to ECF and enjoy your stay.
