I am considering changing our Buy & Sell from the current format to a product called Panjo. Disclosure: My brother's firm are investors in Panjo. That said, I learned about Panjo because they are endorsed by vBulletin (the software we use for the forum) not from my brother. Back on topic, Panjo is a plugin for the forum that creates a new marketplace. When you make a listing, it simultaneously creates a thread in the Buy & Sell subforum just like our current forum while simultaneously creating a listing in iFrame format. There is also a Panjo app (currently iOS only) which includes all listings from Panjo marketplaces on forums everywhere that use Panjo. Some of the advantages of Panjo: -They do the payment processing, which as I understand it comes with some security and support (we currently offer no security or support) -They don't charge any fees to buyer or seller. I have no immediate plans to charge a fee either, so it will be just as free with Panjo as it is now if you are currently paying for things with PayPal -They've got a nice searchable format that lets you search only sales in your geographic area Some of the disadvatages that I see so far: -They only do payments by PayPal -You can only list one item at a time (can be seen as an advantage in some respects) Here are some links which you may find useful in evaluating this option: Nikonites Marketplace (with search, sort, filter, and marketplace management tools) The subforum to which the Nikonites marketplace listings are linked: http://nikonites.com/<wbr>marketplace/ Again, all listings create synchronized, transactional thread posts. Example listing in the iFrame: Nikon Nikkor... The same listing as a thread: Nikon Nikkor... The same listing in the iPhone app (see attached) Examples of more active marketplaces: Audizine / linked sub forums Bimmerforums / linked sub forums Bushcraft / linked sub forums Here is a thread conversation to show member reactions following a recent launch on another site. Let me know what you think!
