OkeyDokey

Sims: Vacation and Sims: Making Magic installed.
-D: So I can assume that the computer versions of me and Marty will soon be able to get outside the house for things other than our jobs?-
Correct-o -- once I start playing. But first, a question. I know Gigs has Sims, and I think Sheley does too. (Sorry K, I can never remember how to spell your first name *blush*) How exactly do I use the expansion packs with my old Sims package? I'd consult my instructions, but I somehow managed to lose the ones that went with Sims Deluxe.
Breakdown: I previously installed Sims Deluxe (Sims and Sims: Living Large in one go). Now I just installed Sims: Vacation and Sims: Making Magic. (Also, I might have Unleashed or Hot Date sometime in the near future.) So, how do those expansion packs work? All new neighborhoods? Will I have to copy my Doc/Marty/Jennifer skins?
Thanks in advance!
