[wp-hackers] Howdy Don't plugin (was Decision time in re: admin rework)

Decided I needed a little exercise:


Now it's a plugin.  Knock yerselves out.  Option page and everything.

I do have a question.  Since the filter only works when there is a  
localization file in use, I wanted to make it so the Options page  
only appears under the same condition.  I tried the following:

function howdy_load_optionspage() {
	global $l10n;
	if( isset( $l10n[$domain] ) ) {
		add_options_page( "Howdy Don't", "Howdy Don't", 'manage_options',  
basename(__FILE__), 'howdy_options_page');

But for some reason the if( isset() ) always results in "false".  I  
copied that test straight out of the l10n.php file from core.  Any  
idea why it doesn't work here?
