The Legacy Challenge Rules

So I've played Sims since Sims 2 and never understood the whole Legacy thing until now, after finally researching it! Thanks to Pinstar & Mystic for putting it all together. I am starting my first Legacy Challenge now. Is there a forum where people like me can just go and chat at times. I'm lost looking at all the options. I know I'm super late to the challenge idea, but am such a newbie that I need to get feedback or even just commiserate along the way. (I set up a stupid additional rule to my challenge - each generation would have children to match their generation # - so first gen would have 1. And what happens? Founder is pregnant, Yay! Founder has triplets!??? Spontaneously! (Did I mention I myself am the mother of triplets? I play Sims 4 to regain a feeling of control... not to have more triplets! :smiley: Anyway how bound do I have to be to any "additional" rules I set up? Cuz, I'm not sure I want to have kill Sims off. :-)
