So it was a teen sci-fi book. I read it in middle school around 2006. It was about an intergalactic alien internet. It started off with a group of human Earth kids discovering that aliens exist and breaking into a top secret lab or military base and teleporting off Earth. At certain points it would cut to a chat session between two alien kids on the intergalactic alien internet. I forgot what the Earth kids were trying to do, but they traveled to a few alien worlds. There was also a tie-in website where you could play games based on the book. My attempts to find it have led to a few sleepless nights.

Oh and it is not Can of Worms which is the closest I get when searching. Thanks in advance comrades!
