Do you think there should be a separate IIN site for younger people?

This is precisely why we need to change our mind-sets, from one based on attaining a particular age to receive rights to do something, to one where rights are earned through responsible behaviour, in an integrated educational program.

For the time being, I have no problem with young people being on this, or other so-called age restricted websites. But, the young people should recognize that this website is an adult forum, and their behaviour should be at least equivalent to that of an average eighteen year old.
In other words, act responsibly, not immaturely.

In the future then, according to plan, young people would need to earn the rights to do a particular activity, through a comprehensive testing procedure, whereby they will need to prove a maturity level in order to gain access to something.
This will, in turn, help to guide them in areas where they might be deficient.
A foolproof system will need to be developed on the Internet, in order to achieve this. This could be part of the test.
A learning process.
