It bugs the heck out of me that organisations are constantly running contests for cool things that I want, promoting it on blogs and specifying in the Ts & Cs that you have to live in the US to win.
The latest example is the TabletGear contenst giving away a UMPC. Great contest, great prize and if you are eligible then by all means enter. I also accept that you may not always be able to include the rest of the world for very practical reasons. However make this clear up front! For the TabletGear contest, for example, you can't get the the terms and conditions until after you register on the site. If you can't include me at least put a link to the terms and conditions below the ad for the contest so I can review them before I invest any time or effort into it.

Hey TabletKiosk - why not give Hugo Ortega a UMPC to give away in Australia / New Zealand
