So i made this uber awesome house, and i want to upload it in MTS2.

Okay, package the lot to a file, you will find this button when you click on the lot.
The lot will then appear in the packaged lots folder as a SIM2Pack file.

After that I don't actually remember what to do. I hope someone else posts and finishes this off sweatdrop

On the neigbourhood screen go into the lot placement mode.
Click on the lot you want to play.
There will then be a button that looks like a house with an arrow coming out from the roof.
Click it and you will get asked if you want to upload to the exchange or to a file on your computer.
Choose to save it to your computer.
The package will then be saved into your Packaged Lots folder found in My Documents> EA Games> Sims 2> Packaged Lots
Copy it from there into a .zip or .rar and you can upload it to MTS2 providing you also follow their rules and regulations. E.G. the lot MUST be scanned with Clean Installer to make sure there are no hacks or mods packaged with your lot.
