How does cracked.io work?

[SwissChocolate]

I think the title makes it obvious, but I'm new to cracked.io and in desperate need of a tutorial, I dont even know how to reply to a post! If anybody has a tutorial to help me, pls send the link(s) in the reply section, thanks in advance! (I didn't know where to post this, so don't delete BEFORE telling me where to post this.)
