I've just added a new article to the Sims 2 University special, which this time covers the creating of custom content. This is one of the last articles already - there will be a couple more, but I've given away most of the info I received. Meanwhile this is already the 9th article so far, which means there is a lot of information. I suggest you check it all out over here. If you've read the rest already and don't want to read it all again, you can skip to the new article immediately by clicking this link. Of course the complete special will stay up as long as The Sims Zone exists, so you don't have to worry about it being deleted soon. If you want to read it again in the more distant future, then go to the editorials archive and follow the link to the "Sims 2 University Special".
