Classified Ad Scripts are a great way to let your users
interact with each other by letting them sell or trade their stuff.
Good thing about this script is that it has a feature that only lets ads be
up for a certain number of days. Good if you want to charge money for a posting.
Also has a 'free' section. Includes a basic search engine for finding ads
quickly. Click for demo.

Not as many features as Selena's script but it is definetely worth checking
out. Stores address information about posters in hidden files to keep their
identity secret. Unlimited number of sections and very easy to set up and
maintain.

Classified Ad Script - By Selena Sol
Nice looking script that devides the classifieds into sections. Option to
make people 'register' before they can post. Also has a nice search option
that lets other people search through the posts. This is useful if many
ads are posted to the script. No demo available.

Not a very pretty script but it gets the job done. Only has two page outputs...
one for the ads and one to enter an ad. One good thing is that it has a feature
to only have a certain number of ads at one time, this way older ads are automatically
removed. Click for demo.
