Hey man, we're just going through a tournament right now to establish champs/rankings but once that is done we will be letting more people in.
post your live ID and weight class of choice in the sign-up thread linked above. check out the rules when you have a moment and check back to see what's up from time to time. Should be a week to ten days before we're putting together the first event, i think.
You can also head over the the teams forum and join an existing team, or create your own. Get the IDs of the guys on your team and get to training up for your first fight.
