Instructions for site admin plugin? Or something like that…

I’d be interested on a very simple plugin that would ad a question mark -ikon (or such) to the write post page. If a the site admin haven’t updated the page in a while and cant remember “how the hell I supposed to do this” he/she can click the help button and there would instructions.

I’ve been using this hook to insert content to post editor:

<?php // auto-insert content to post editor
function my_editor_content($content) {
	$content = "<h3>Some text here to help the admin remember which category and which customfield etc.</h3>.";
	return $content;
}
add_filter('default_content', 'my_editor_content');
?>

But you know, it’s a bit clumsy way to do it.

Cheers!
