If you do a lot of business and are looking to arb the pit and screen then call up any Ag clearing firm and they will hook you up with someone on a headset.
Kiwkpop have a 45 minute video on the corn market on their website. Not really sure why but they do. I listened to it though I dont trade corn seemed alright but I was bored. Might help newbies
i have traded some corn. i really like it it is a very smooth market to trade. i prefer YM, and that is my bread and butter (cornbread otoh...)
