...that's what I thought as well. I've not used google adsense before, but I've set up my account now. I searched for eBid, but can't work out how to do it. We need an idiot's guide of how to do it!I don't suppose you can use those links in Emails, can you? Would it have to be the buddy link in Email signatures? I don't know if you get anything for referring new buyers - could miss out on buddy links.
Also, if you have to have your own website to use adsense, that excludes us from being able to post the referral link in forums etc where most of us do our plugs.
