I've mentioned on a few other threads -- I used to work in a graduate admissions office, where basically I was the transcript person. I used to be the one emailing people, etc. Send them a scanned/unofficial copy. If they have that they'll go ahead and send the unofficial copy for review. They wouldn't hold up the process for that reason.
On a related note, I'm anxious because on my main transcript there was a third, blank page. I deleted this page to make the file smaller when uploading, but on the bottom it reads "page 1 of 3" etc. I'm afraid they'll think I'm hiding the last page for some reason... though the degree conferral and final gpa on the front should confirm there are no other classes. :/
