this happens maybe twice a year, so get in before it closes at midnight in the states. it's a private tracker (you do have to maintain a ratio above .5), and it's fairly awesome for most releases and full speed downloads.
start off slow, don't download more than you can upload.
you have ~6 weeks to get your ratio to .5, if you like, you can also donate for quota.
it's a strict system, read the rules and abide by them and you'll do just fine.
I've downloaded over 900 gigabytes and uploaded over 1 terabyte of data from this, go hard or go home haha
also, tomorrow is double upload day, so whatever you download tonight, leave seeding (uploading) tomorrow (in the states, so lunchtime-ish onwards), and you will get 2mb per 1mb uploaded
