The AL events are all registered under "Thomas Valley". Googling his name and "Adventurers League" gets you this, among other things: http://dndadventurersleague.org/preparing-for-a-convention-adventurers-league-game/ And, from that link, mwisconsin is a name on this board. So, if you search this board for members and PM mwisconsin, I think you'll be talking to the man.
Here is a link to the browser version of the e-mail Tom sent out earlier today. You can subscribe to the Gary Con AL DM mailing list by clicking the subscribe button in the upper left corner. You can also access the Matrix of all the slotted games, allowing you to find games that need DMs and sign up to run something. And yes, Thomas Valley, aka mwisconsin, is the gentleman who is heading up the AL room. http://eepurl.com/cw_IkL
