I was thinking about the word of those things which are published in craigslist.com and whether if I should call them ads? list? commercials? notice? promotion? flyers? or something else.
To clear what I say, where I live, there some daily extra pages published with newspapers in which people and organizations publish their needs or what they can offer other people, as one sells a car or another needs a teacher etc.
What are these kind of things called?
