Looking at so many new names in-game, I think you all are already doing the great job bringing them in.
But, then what happens:
1. We know lot of rules, but they know none. They wonder why everybody's killing their trader. Wow, how many factions! But why all shooting at me? What's contraband, I bought this goods fairly, for huge moneyz!? What does it mean: //stop ooRP in system?
2. Ok, they buy their first snub. Why my new shippie works on 90%, wtf? Hey, why I die in 20 seconds every time?
3. They trade more and get a GB. Why shooting others with a GB is not fair? They were shooting on my bomber yesterday!
4. They trade more and get a BS. They get sanctioned for swearing, or ganked, or who knows what.
5. They leave to play something more simple (we all do that too, time to time).
This will be like that imho, until we provide them solo player Disco, where they would grind knowledge, ships, skills and even fairplay logic.
Or we can give them systems we don't use (like driving school) and after reaching some point they could apply to be tested if are finally ready for starting in Pennsylvania.
