Apology (for rule no.3)

I made a comment that rule no.3 is stupid
well sorry, i got it wrong,
it never comes to my mind that this site can be an instrument of suicide
yeah, i've read some wherein you can see, that there's a tendency of suicide for them

now, I'm up with rule no.3(well i can't call it as a rule, but a note or a reference)
yes we can be a help for our fellows who are in danger
but professionals are really help.
