Gradumatate?

So, I look in my e-mail today and I got this notice about our 10-year high school reunion:

Help us find 37% of our missing graduates? I don't get it. Why don't they want to find all of the missing graduates? Do they only want to find certain people and they don't really care if they find Justin Ardolf or not?

Or, do you think they meant that they can't find 37% of the people we graduated with? Yeah...that's probably it, though apparently 27% of the people on the graduation committee might should not of graduated.

Me English-speak good.
