g-force2k2,
Consider the review system as something for hackers to aspire to. If new hackers get their feelings hurt because their first hack did not get reviewed or it was given a 'poor' review, then perhaps those users are not made out to be php programmers... I would think that to be good, one needs to be open to criticism and more importantly, to learn from what is said. Basically, it goes hand-in-hand with maturity... mature people will accept it, others... well... we've come full circle now to my other suggestion
I'm afraid that having clan-systems will cause divisions. It is human nature and something that has already kinda happened here... one only needs to look at the whole arcade drama to see how some groups can cause division, even when that was not the original intent.
FWIW, these are my own humble observations here so take them however you want
Cheers,
~Regs.
