Wait a second... The have closed the server!!??? Whhyyy???!!! I can't read well.. Is it going to start again??....
Catch up with news about Gintama, read the Gintama manga in both original b/w and full color and watch raw episodes of the anime. You can even read the novels!
I think that my favorite feature is the unlockable character icons; once you read a certain amount of chapters containing a specific character, you can unlock their icon, to use when commenting, and their character information page!
It's awesome. I love Gintama!
