If a Sim interacts well and gains enough daily relationship, he/she might be given a beneficial network.On the other hand, making a bad impression will make the Sim be given a penalty network.If a Sim makes a good impression to a townie, something good can come to them from it. Inexplicably, these benefits are not available to young adults, even though a young adult townie may be the one giving the benefit.
Reputation is determined by one's relationship with other Urbz. Socializing with Urbz to build relationships will increase reputation.
Rep is displayed on the HUD and when it gets to the big star, the Rep level will go up.
Secret networking can only be received by newly met townies; if the townie has given a network, or if the townie didn't give one at the first time they met, he/she will never network again.
Other than townies, apartment neighbors and roommates may also give Sims a secret network.
Secret networking does not depend on a Sims reputation, though high reputation does increase the chance.
