I am also keen in taking part in this, have sent you a PM.
On a side note, just my 2 yen about the picture (Wah you damn pro lar your csi skills)
I for one do not see anything wrong with it as there has been no intention shown to cause any harm to them. Hell, even if his IC and address is disclosed I also see no harm since he has brought this upon himself. This is Singapore, you are accountable for your own action.
Even if someone does threaten harm, he can simply report police and the threat can get arrested. At any rate, he has brought this upon himself. This reminds me of something I once heard, about how children will bear the sins of their fathers. Thus, people should always think carefully about their actions.
Just to share a story.
I myself have been somewhat tricked before (at work). I used to work at a place that conducts courses, and long story short, a participant signed up, but kept delaying payment. Ultimately, we could not contact the person. Doing abit of CSI work, I found out she was in prison, for yanking her maid's teeth out (it was in the news). And to think I had even took the time to visit her home to try and persuade her to pay up (wasted trip).
Her daughter (who was also imprisoned before her for the same crime), tried to pull the same stunt on us after her release, by enrolling for the same course. When I noticed the familiar address, I did some investigation and found out who she was. Needless to say, I was all too wary and demanded payment for her mother and herself by before the 1st lesson, or else she would not be allowed to attend the course. Needless to say, she did not turn up at the last minute, probably feeling guilty, wasting our catering, time, effort and coordination to prepare her materials.
