There are two ways to stay anonymous:
1) The safest way is to use contact form (there is one in the middle of the right sidebar). It doesn’t store your IP-address and you don’t need to give us your name or email adress.
2) Create a new gmail fake account and send us your rumors at 43rumors@gmail.com!
Remember we mostly will post rumors/news that have been confirmed by other sources.
P.S: Of course if you are under NDA it is forbidden to you to share your informations! Keep it in mind!
ONE MORE THING: Somebody knows something about the Fuji microFourThirds camera?
