The big event for Marvel Comics this year is being called Civil War. I'm actually interested in a Marvel Event for a change. 

From what I can tell, the premise is this:

A young team of super powered heroes are taking part in a reality show. They raid the hideout of a bunch of supervillains, thinking to bring them in. The problem is that this hide-out is a normal house in the middle of a quiet neighborhood. During the fight that follows all but one of the heroes dies, and a bus explodes, killing quite a few innocent bystanders- including children. 
As a result of this, the public decides that they've had enough- they want someone to be held accountable. The government passes a hero registration act, and basically says "Look, if you've got super powers, and you're acting in a hero capacity, you need to come forward and register your name, etc. 
The various heroes in the Marvel Universe have differing opinions on this. Iron Man supports the move- which isn't a surprise since he reveiled his identity before. Captain America opposes it. Spider-Man is supposedly caught in the middle, torn about which side he falls on. 
Fans have been encouraged to take sides in the debate (which is, rather obviously, a take on the "How much would you sacrifice for a sense of safety?") in a variety of ways. The adverts for the series have taken the form of bold <a href="http://www.alphaflight.net/news_archives/whose_side.jpg">ads</a> asking "Whose side are you on?" Forum goers and BBSers have been encouraged to display their choice with banners like this:

In honor of the event, I took a few minutes (literally, just a few) to make a couple of banners myself. Wear them with pride, my friends. 
Wear them with pride.
