I know Emma quite well and consider her a dear friend, so I can let everyone know with certainty that something big is going to happen with Emma's site/blog before the end of the year. So everyone watch her site to see what the big news is going to be.
I am pretty sure everyone will be as excited as I was when I heard about it.
https://emmas-simposium.blogspot.com/At Emma's site you can get files that the creators have left the community, request files that you can't find, request patreon files or pay file or both. You can request anonymously and you can donate files that you want to share with everyone else. Her site is kind of a go all for anything sims 3 or 4 related that either costs or is lost.
This is the link to her request page that says about how you go about requesting files from her and her team.

And if you can't find what you are looking for, hey go ahead and request it, what could hurt, you getting told she can't find the file or she gets the file for you. Either way you don't lose anything and can possibly gain something.
