<h3>The Big Idea</h3>

The ArsDigita Community system contains the photo.net classified ads
module, which has processed more than 100,000 ads since its inception in
1996.  The module includes the following features:

<ul>

<li>multiple domains per ACS installation, e.g., photography and travel
can cooexist

<li>multiple categories per domain, extendable by user or by site
administrator, depending on configuration

<li>multiple moderators per domain 

<li>auctioning available, configurable by site owner per domain and also
by user per ad


</ul>

<h3>Publishing Decisions</h3>

Via the ad.ini file, you can enforce a lot of publishing decisions,
e.g., "don't allow anyone to mention eBay" or "how many bids does an ad
have to get in order to be considered a hot auction?"
