Xobni is an awesome plug-in for Outlook that adds social networking, statistics, and a very fast, useful search function. A few months ago, I filled out a survey for them, so they sent me a T-shirt.  Today, unannounced, another T-shirt landed in my mailbox!  No idea why.  Maybe they’re re-branding from brown to black, so needed to send me a different colour?  Do I now have the only two Xobni T-shirts in Australia?
