i dont know how to put any of them into my game. i download them as .zip or .rar files, but then i dont know what to do. please help?
if you have winzip or wiinrar program...right click take this file a little right side  and then choose extract the file here! and there will be "filename.package". move this file into your 
"c: documentssettings/user/mydocuments/eagames/thesims2/download/" 
if you don't have "downloads" file create one in
"c: documentssettings/user/mydocuments/eagames/thesims2"
 I hope this gonna help you
