This is probably something really dumb that I'm missing, but I can't seem to find a way to write articles for my sim's career! She has the option to write non-fiction books, but that's not the same thing, right? I checked in the computer(the one she got at writer level 2) under the "write" and "career" menus, but there were no new options there.

You have to interview another sim first. It's under the friendly options.

Ah, thanks! That would have been helpful to have been said in the promotion pop-up, or in the hover-text when I look at my sim's career.
