NRaas Story Progression Career module has the option under 'School Options'.

Why not? Is it because it annoys the Alphatards, or because you're afraid that the shock of getting a helpful answer might just kill her?

Sita, it's part of the I heart the Fifties set, but I don't think it's available separately. This is the only link I found:

I took another spin at the "Make Me An Offer" machine today, and I believe this shirt has not been shared yet.

I got three more of the 'exclusives' today and put them on Mediafire for anyone who's interested. Two more shirts and another ridiculously large hat file.

I've played it since it was out. It is small, but there's plenty of room to have all the necessary community lots, especially now that you can use combined rabbitholes or rabbithole rugs.
I'm thinking of adding a port or two, just so it feels a bit less cut off from the world.

I did remove some spawners, and there were trees somewhere under water for some reason, but it has run fine ever since. With a ton of cc.

I don't know about the downloader, I tried downloading it myself from another account and didn't get that. Must be one of the Mysteries of Mediafire.
The hat file is 10,664 KB, and all I added to the zip was a very small jpg. Apparently 7z can't compress it any further. No idea why the Store makes their hairs so huge. It's not like they have incredible detail or anything.

I have two of them. It looks like there are ten in total.

The only place I've found it in the past is in the "When Worlds Collide" Compilation.

All untouched Sims3Packs.

What's there to be confused about? It's two nieuw short-term-only Diesel clothing sets, and a Simpoint bundle with free Diesel outfits. Three different sets.

Here you go:

No, but if you're a member of N99, somebody there copy/pasted all the relevant text into its own special forum topic. Not sure why she doesn't just share the PDF...

I have about half of the medieval bonus items.
Still missing the sofa and loveseat, a coffee table, one single bed, the wall shield and LordLionBowel Feasting Slab table. (The warehouse crate was shared already.)

All unmodified Sims3Packs. Pictures on this site:

I'm broke for the month. Any chance of somebody else picking up a few more?

Yes, somebody does have the new Katy Perry bundle items.

Unmodified Sims3Packs, all three in one zip:

Those arcade games look sort of cool. Not worth buying 50,000 points to get them, though.

New Simpoint "Mystery Bag" items. So far I snagged three, a bar stool, a bar and a dining chair that apparently go with the Honeymoon Suite set that was their "treasure hunt" gift a few months ago.

I didn't get pictures - they showed up as question marks in my PH.

If there's a 'rainbow wheel', this site offers no help. Mac users are on their own here. (Unless I missed something and Windows now has its own little beachball of doom?)

It would have helped if you'd said you'd already done that - to distinguish you from the tards who can't be bothered to look for themselves. 
Did you 'drag and drop' the files onto the program, or did you go through the command line? I found that for me it only works when I decrapify on the DOS command line.
You could use a batch file if you have a lot of files to do.

You don't need to buy the bundles. Just pretend to buy, go to Paypal, log into Paypal but *don't* confirm your purchase. Then click 'cancel and go back to EA' and most of the time you get one of the gifts. You can get them all this way, but you will end up with a truckload of crappy badges.

I think it's probably easier to just extract all the Sims3Packs that are shared here already.

Nowhere. You need to find all the separate files and sets for teen clothes. Nobody ever made a file that includes all the teen clothes, or all the sofas, or whatever.

Great, thanks! I guess the search system at MTS had another hickup. It was one of the first places I looked...  

Edited to add another question: I installed a few compilation sets that include the sets you unlocked the stencils for, but now the stencils no longer seem to work. I'm using decrapified Sims3Packs and installing through the launcher, and I've put the decrapified unlocked_stencils files in my Mods folder. The objects that should have extra stencils now show up as a .package file that I can't click.
Does this have to do with the fact that the files are now packaged differently, or is there something else I'm overlooking?

Apparently there's a hidden stencil in the Scarab Rejuvination bed - the one that came in the Explorers' Loot WA registration bonus.
Not sure whether a stencil can do something about the crappy textures on this bed, but maybe it will hide the damage just a little?

I only found a picture of what it's supposed to look like, not a mod to actually unlock it, and I'm not clever enough to do it myself (can't even get s3pe running on my Mac), so could you please take a look at it if you have the time?
