Hi there! I don’t really use the Lot Adjuster, although I have in the past. (I usually can’t be arsed to exit and reopen my game in order to use it. XD) For the most part I just deal with the standard Maxis lot sizes and they’ve served me well thus far. Or I use one of these lots by MaryLou that are already shrunk/adjusted. 😀
The LotAdjuster is not as scary as it looks, though, I promise! I’m pretty sure I just followed the instructions in the download thread at MTS and it was pretty self-explanatory. I’d advise trying it in a test hood first and backing up your neighborhood, just in case! (It’s a good practice to make frequent backups, anyway. :D)
