Thanks, refurb. So there is essentially no way to find out whether my GMAT and transcripts got to them via mail? Oh, well, I'd rather first get invitation anyway

That was my concern too, but again don't worry. There were a few people here whose applications were missing transcripts or some other part and Ross got a hold of them and requested the missing info.
I actually didn't get my interview invite email! I got a call the week
after the last invites went out asking me if I'd still like to interview!
So basically, sometimes things go wrong but it's not like Ross will just toss your application if something is missing!
