as PC said you have to wait till season 2 starts to sign up, now there still are some KOTH races being ran, there will be a post, usually by Dig or Casey telling of the event. the track is usually released the day of the event,and they will tell you who to contact to qualify...thats the hard part.IF you qualify and get in the event you will be invited into a chat on AIM and br givin the rest of the info you need there. thats it in a nutshell, also go to the tutorial section, then rigs of rods,and read "new to sim-monster" post.
