Ok, I think this was somewhere earlier in the thread, but I couldn't find it. How do I upload the house? I have it on my upload section of the sims 3 launcher.
EDIT: Just incase it matters what browser i'm using, I usually use safari, but I have firefox and google chrome if I need to use one of those.
I'll walk you through it.
Step 1: After you've exported it and you're in whichever thread you want to upload it in, make a post. If you want to upload in the first post of a new thread, start a new thread. (This is on this forum, not thesims3.com)
Step 2: Fill in your post.
Step 3: Click "additional options" underneath the post box, but above the Post/Preview/Spell Check buttons.
Step 4: In "Upload attachment", press Browse.
Step 5: Browse to the file you want. The path is different slightly on different Operating Systems, but it should be something like "My Documents > Electronic Arts > The Sims 3 > Exports". Select the file and press "Open" or whatever is above the Cancel button in the bottom left.
Step 6: Press Post in the post window that appears.
