How to post an ad on Craigslist with clickable link
From PropertyMinder WIKI
Below is the format for adding a clickable link on a Craigslist post. The http address will need to be changed depending on the Realtors website address.
<a href=http://yourdomainname.com/?target_url=http://yourdomainname.com/MyListings target=new>Click Me</a>
When you are entering the html code on your post, you will not see the Click Me link until you preview your message.
