If you get Merola's multi purpose painting, you can change the werewolfs personality back to the way it was. It's just a pain to have to do that all the time. You can get the painting at www.simchaotics.com. I love that painting!
I also like her meshes but don't like the fact that most of them are pay. I make clothes on free clothing meshes because I enjoy sharing my work with everyone. Besides Warlokk is a fellow insimer and thats a plus because people don't have to hunt for his meshes.
The most I ever had was about 6 gigs. Then I cleaned it out and ended up with just over 4 gigs. Then I installed "Seasons" , had some problems and lost everything. Including my own creations. So I now I am back to 1.5 gigs. I'm trying my best to keep it low but I don't know. The booty has so much stuff I gotta have. Oh well...
