It automatically searches for all eBay links in threads and makes them an affiliate link.
Have you tried? I have not had the time to play with 3.7 yet, but as mentioned in my other modification threads, once vBulletin hits 3.7 Gold, my modifications will get there eventually. I'm not doing anything before 3.7 Gold, as there are probably lots of quirks before it does get there.

So I'm a bit confussed how this function works. Lets say some one posts a pic with a link or a click here link to a URL from ebay, is it suppose to add your PID to the URL?

I'm just curious what I'm suppose to see to know it is working?

1. Yes, it redirects the URLs through the eBay Affiliate program.
2. The links change, and you'll see your ID in it.

OK I've read the entire thread, signed up for Commission Junction, and then eBay on CJ. I know my AID and PID and I've installed this hack.

I've put in my PID in the Vb Options, but the link contains a AID that doesn't match mine. Where did that AID come from? Does it earn commission for someone else -- and do I earn commission with my PID but someone else's AID?

The AID is eBay's AID as seen through their link generator.

So I should not change that to my aid in the template?

Bug.... the following URL turns into an afilliate link

The AID that is used in my modification is provided by eBay, but if you think that you should be using another one, feel free to do so.

installed on 3.7b4 and working perfectly

Hey, I think this plugin is the reason I got this error:

Note the triple-slash. When anyone has a signature with an url with a triple slash, this warning appears at the top of the page twice. I'm not sure what line 21 is referring to.
