Panjo is legit. In fact it comes packaged as part of the forum software I use here. You can enter Classified Ads one of two ways: Either enter the Panjo Marketplace by clicking on "Classifieds" in the upper navigation tabs, OR click on the corresponding Classified FORUM in the forums list (e.g., MG Classifieds). Either way, your ad gets posted in both places (the forum and the marketplace - they are linked).
