#2 - As you can see (in the code below) I'm only changing the_title and looking for "exclusive" or "mp3" or both. How can I COMBINE this function?

this is my code:

# write EXCLUSIVE Correct
function writeexclusiveCorrect($content) {
$content = str_ireplace("exclusive","EXCLUSIVE", $content);
return $content;
}
add_filter('the_title', 'writeexclusiveCorrect',1);

# write MP3 Correct
function writemp3Correct($content) {
$content = str_ireplace("mp3","MP3", $content);
return $content;
}
add_filter('the_title', 'writemp3Correct',1);

And what needs to be changed in the default php.ini file?

Is there a way to show a list of all filters being loaded?

The question I have is say you do a series of plugin/function/shortcuts like this, is there an overhead?
or is there any issues with that type of plugin shortcut?

Is there any additional security or any additional code I should add to this type of simple admin-less plugin?

As is, my WriteMyPostalAddress test using dreamweaver created wysiwyg table, code just plopped in, works great!
