Wow. Jamie has added a cool new feature to the TestDriven.Net site. You can now see the list of referrals you sent in by links. It looks a little something like this:
I found out after getting an email from the site that I was added to the "Referrers" role(looks like he's slowly working his way through the referring user list to add them to this role). After logging in I saw a new "referrals" link on top and got a link to download either an image or an SVG file. An SVG file is a new format for displaying graphics which is based on XML. You can view it using free SVG viewers ( used the free one from Adobe).
Cool work Jamie!
