Because FogBugz does not allow the user to delete things, I've always found it pretty odd that you use the term "Delete" in numerous places in the user interface.
It seems objectively misleading--if you can't delete a thing, then why would the term "Delete" show up in the user interface? Wouldn't "Deactivate", "Archive", "Hide" or something similar be more descriptive of what is actually going on?
It doesn't seem like you are doing yourselves any favors by using the term "Delete".
