- Enter Edit Town from the Options Menu.
- Select the lot you would like to upload by clicking its Map Tag. Click the "Share" button.
- Give your lot a name and a description (be sure to mention that it is an entry to the Carl & Pam's Sims 3 Forum Building Contest) then click the check mark. After your lot is successfully exported, a pop up will direct you to the launcher to upload to The Exchange.
- After opening the Launcher, find your Lot by clicking the "Uploads" button. The status column will inform you when the item has successfully uploaded. To see your Lot, go to My Page and then My Studio. Once you click on the lot you will find the link to it at the top of your browser.
Note: Once I'm able to return to my regularly scheduled life, I'll make my own tutorial on how to do the above steps. Until then, you may want to refer to this tutorial on the official Sims 3 site:
