| - | === Create an Anouncements Category === | ||
| - | |||
| - | Use Wordpress and create a category called 'announce', and populate it with a few posts. Test to see that the rss feed works. | ||
| - | |||
| - | If you're using some sort of nice URLS, it'll look like http://www.yourblog.com/feed/announce | ||
| - | |||
| - | If not, it may look more like http://www.yourblog.com/?feed=rss2&category_name=announce | ||

| - | === PHP / DOM === | ||
| - | |||
| - | Put this in **includes/templates/YOUR_TEMPLATE/templates/tpl_index_default.php** (we put it at the very bottom). | ||

| - | $post_text = substr(strip_tags($post_encoded, '<p><a><blockquote>'), 0, 500); // strip out common tags here | ||
| - | if($post_text != strip_tags($post_encoded, '<p><a><blockquote>')) | ||
| - | { // add read more tag | ||
| - | |||
