well, i nvr post my contact number, my address, CC number etc
right? 
i nvr even state wad sch im from.
Though im not sure about you, to me i find what i posted
something that can be shared with strangers.
and btw, due to my past passion for hardwares, i'm a regular
forumer for singapore Hardwarezone forum too. Though im using a
diff acc name for it.
I know what school you are from, not hard to figure out and
there are ways to find out details about a person through contacts.
Not a bad school right, 1 of the better non independent schools out
there.
Considering i work with youths alot and know youths from many
schools, borrowing a school magazine to find out what class you
are, what is your picture or even getting ur details might not be
that hard though i rarely could be bothered to.
