[BuckeyeParalgl]

Buckguy is trying to tell you that you referred to your status as a graduate of the University of Michigan in the plural form of the original Latin root, and that you should choose the appropriate singular form instead of the plural.

I will be the first to admit that though I point out errors that other people make in writing, my grammar is far from perfect. Take that FWIW, and good luck selling those tickets.
