On your menu, click on "Create Content". This will open up a page that lists the available types of content you have permission to create (Blog Entry, Forum Topics, etc...)
Click on the link that reads "Classified Ads". From there you will be taken to a page where you can fill in the needed information. Ads can be no more than 500 characters long, so be sure the ad is short and sweet with as much detail as necessary.
When you've finished, click "Submit" and you will see your finished ad.
Please note - at this point, your ad is viewable by you only. To make it public, you will have to pay (via PayPal). However, you may edit and reedit your ad as many times as you like before publishing it.
