Useful hacks and fixes

All things Christianlov - for the All-In-One NPC:s and much much more.
Simlogical - for a sim school, and prison and lots of other extremely useful stuff.
Inteen - because the girls back in historical times married in their teens, as a rule.
Insimenator - to make tweaks in game.
Check this thread at MATY for updates to Pescados hacks.
2jeffs shelf at the Inteen-site - I play with ACR, visitor controller and of course the smart beds mod, for bed sanity.

Face Default Replacements

Zazazu's Face Default Replacements (used all second spring/summer/winter/rotation)

Useful programs
The SimEnhancer, a program which helps me to tweak stuff out of game, and to make backups and get clones of sims I want to reuse.
SimPe - without it, what would sim modding be? Nothing.
Jfades Collection Maker and Wardrobe Wrangler, and more.
SimCamera - without this program I would never have been able to make this site.
