Needing a certain script

[carrie911]

Alright, thank you c:

Which mysidia adopts script version should I download?

All I really need is -
a system where you can buy and sell items with other users. And buy items from the store.
Buy and sell horses.
Where I can add pets onto users accounts when they win a adoption form.
The pet bio thing (will try to add myself)

That should be it then after that!
