That's what thousands of applicants to the University of California, San Diego just went through.

Imagine it:  You apply to a university and get rejected.  That's hard enough.  But then to receive an e-mail two weeks later saying you were accepted, only to find out you really weren't - that the acceptance e-mail was a mistake - that's got to be emotionally brutal.

For a lot of reasons, the university can't just go ahead and accept every victim of the mistake; there are simply too many who never qualified.  But how would you react if this had happened to you?  Could you just forget about it, cut your loss and get on with other college plans?

As representatives of the world's 20 leading economic powers meet in Britain, we're bringing you coverage of everything from the goals of the event to the protests against it.  These are particularly challenging times for G-20 reps because most of their countries are in the same boat as the U.S.  You know how we've been talking about struggling businesses, a weak stock market and increasing unemployment?  It's a scene repeated around the world.

Now you probably have some ideas on how things can be improved...and here's your chance to tell us!  What would you say if you were given the spotlight and microphone at the G-20 event in London?  What ideas do you have for fixing up the world economy?
