You can get connected at http://www.mgoblue.com/sports/m-footbl/mich-m-footbl-body.html .
I have been connected for quite a while, though I can't remember how (Facebook?, Twitter?, Text?). All I know is I get texts for a chance at free tix, etc. I just signed up for recruiting updates as the LOI's come in.
I replied to the text that they sent me UMSIGN to 51234 to get in.
