I've got an idea, which I'm not sure follows the upload guidelines. They state that any sims uploaded to the site must be a .sim file.
I opened CAS, the premade sims bin and created 19 households in a .package format, which reside in my Library folder. I want to upload them all to MTS in .package files. The main idea is for users to have diverse, pre-made population ready to move in so they don't have to create any new sims to populate empty worlds and don't want the "pudding face" effect when they turn on immigration via the default EA SP or Nraas or any other mods like that.
I know lots are supposed to be in a .Sims3Pack format, but what about whole families? Is it against the rules to upload those families from my Library folder in a .package format?

It would be great if you could do this. Your Sims' photos look really good.

Thank you Actually I meant the premade sims you can see in CAS, when you open the bin. I have them all divided into 19 households with 8 sims in each of them. They're all in the map view sim bin and I want to upload them to MTS in case someone wants to move them in immediately and enjoy a diverse population with no "pudding faces".
