N.B.:
for the *classic skin* (standard.php), you must go in includes/skin.php --> function
doBeforeContent() --> comment the lines :
$s .= $this->pageTitle();
$s .= $this->pageSubtitle() ;
for the *cologneblue skin*, open skins/cologneblue.php --> function doBeforeContent()
--> comment the lines :
$s .= $this->pageTitle();
$s .= $this->pageSubtitle() ;
for *nostalgia*, open skins/nostalgia.php, then do the same
for *chick* and *simple* if you removed the title in monobook.php, it's removed for
those one as well (inherited), but you'll have a "from nameofyourwiki" tag
line. You can remove it in monobook.php :
remove this : <h3 id="siteSub"><?php $this->msg('tagline')
?></h3>
(I guess you could also remove it with chick and simple main.css using the corresponding
class or id using "display: none;")
