Be warned ... going a bit off topic here ...
I totally agree here ... the cancel button should not be there, at least not in that form. The main action button (ADD) should be different from the CANCEL button, different color or something. As it is now, they are the same, and users can easily make the mistake of clicking CANCEL instead of ADD.
You could for instance make the add button stand out a little more with the C9 yellow color, or change the cancel action to a regular link, not this button feel it is now ...
So, if this message appears in this thread, I was smart enough to click ADD instead of CANCEL .... others might not be so lucky
