Yeah I can see how it would be annoying. I know I wouldn't be too happy if I had to copy and paste since I also spent a good deal of time on the format. However, I think that if I really wanted "THAT" job then the few extra steps, reformatting, etc. would be worth it.

Turns out it did help screen a bunch of people that were seemingly just spamming every posting with their resume along with one who copy and pasted an entire (unedited) email mail chain she used to apply to another position...

Overall I'm not very happy with the performance of the posting, maybe it's my fault...
