It is highly inconvenient.
I'm tryin' to figure out how to make all these different grids line up, and it's a big pain in the butt because nobody can agree on what to do when you get to the poles.
EDIT: And while I'm complaining, I would just like to point out that we are in the freaking 21st century now, there is no need to include rows of underscore characters in a form indicating where I'm supposed line things up on the typewriter when I fill it out. For that matter, there's no need to email me a bloody Word doc to get the information, either. Do they expect that I'm going to print the thing out and fill in my answers with a quill pen? Argh!
