Check out the last parameter (none) in the Template Tag, comments_popup_link().
[edit]
Note, on the WordPress Default 1.6 theme, the comment_popup_link tag in index.php only utilizes three parameters, so consider there is a 4th parameter and a 5th parameter not used there.
Basically, in « wp-includes/comment-template.php » I do this:
#function comments_popup_link($zero=’No Comments’, $one=’1 Comment’, $more=’% Comments’, $CSSclass=”, $none=’Comments Off’) {
function comments_popup_link($zero=’No Comments’, $one=’1 Comment’, $more=’% Comments’, $CSSclass=”, $none=”) {
Would most people prefer to leave it blank?
If in a future version you include language libraries, this would be a good place to change it.
Thanks!
