Yeah, technically it's not "by invitation" because they do e-mail it to everyone, but that way only those who have applied have access to it. The invite will be for the $50 file review fee after they've gone over your specs. Right now the entire server is down for MSU Vet Med, our ITC department is less than on top of things. Since it's labor day weekend, I wouldn't expect an e-mail for a submitted app until at least Wed.
I love this school, but I can't stand Groupwise or our Tech Support, they're pretty much useless.
