Added the first one. No threads in the tutorial forum, though, please. I want the hard to find ones, because they weren't made up as a proper tutorial.

Believe me, many of those are hard to find, too. It might be nice to say in the first post that some harder to find threads are posted in the discussion or something, because there are some great things there as well.

Here's a mini - tute I did on how to make an empty pool/basement using Grid Adjuster. http://www.modthesims.info/showthre...190#post5500190

Is that tutorial different from the two tutorials on grid adjuster and basements that I already have in the first post?

Someone mentioned it and that it had been hard to find.

Thread still being updated? Around a year back I made a picture tutorial on using Advanced Renamer to rename a neighbourhood:

Added. (Oh come on, it was almost 7 chars)

I once saw a mini-tutorial on fixing the OFB shelf glitch (where glitched custom objects placed on an OFB shelf teleport to the corner of the lot when restocked). It involved changing a few values in SimPE. Does anybody know where it is?

@Charity, Monique's Computer Edits: How to Change the Interest Rate and Only the Current Family Gets Charged Interest was explained by Radium and then I added step by step details and pictures here: http://www.modthesims.info/showthre...049#post5628049

Added to the first post.

@Charity, HugeLunatic taught me how to make a custom garage door rotatable:

1. Open up the "Function - Init - Common" bhav of the door you want to edit.
2. Find the line that restricts direction perpendicular to street (it's usually the last) example: "0x15 (21): [prim 0x0002] Expression (My flag field 2 Set Flag Literal 0x0007)"
3. Click on the pop up wizard (hammer & sickle button) and change "set flag" to "clear flag".
4. Commit File, save, & test.

Came across this post; don't want it to get lost.

Sunrader explained How to add Lots to the Specialty Lot Bin.

Not really a tutorial, more like a quick take on how to get rid of strays showing up on edited CAS lots (in a thread of a mod that gets rid of freezing Sims on custom CAS lots as well!):

My two cents worth, even when it's not a tutorial:

In order to hide any lot from the Lot Bin that's a 'staple' lot (such as the vacation hotels), rename the lot to add ".off" to the ending.

It will not show up in the lot bin.

This is useful when you're playing a themed hood.

simsfreq's quick tutorial on how to get rid of social class townies from AL (Gearheads, Bohemians, Jocks, Techs, and Socialites):
