Thanks everyone. I just assumed that I needed Gold to post, but lo and behold, I could get on the AH just fine. I did check my reserves and I have one 85 DRob and an extra 98 DRob. Not sure what he goes for, but would be willing to let him go for a reasonable offer.
I was just looking at my team, as I haven't played in a couple of months and my 450K in coins sure goes a lot further now than it did when I was last online.
Unfortunately, I was disappointed to see that there weren't any new UofM players since I was last online.
