Urgent Polynomial Assignment !!!!!!!!!
Speaking in terms of me getting out of the ocean and skipping across the beach, it does not matter how many '!' you put in the title, or how urgent your assignment is to you, I get out when I get out, and I check the forum when I feel like it. Just like the other people who volunteer their time here.
On the other hand, speaking in terms of common courtesy, it is not an acceptable practice to do things like all caps the title, or add multiple '!' on the end. Drawing this kind of attention to your post will actually cause many people to complain about your title rather than offering assistance with the question in your post, or ignore the post completely.
