I'm making websites for a company where users have to "register" with names and a lot of different information to attend the event. (It's a video-event - info would be name, e-mail etc.) I now got a Wordpress webpage, at the blanket doesn't necessary need to be on the site, but can open in a separate window. I need to, somehow make it easy for admin to look at the users who registered, send them e-mails etc. Make a list of everyone who register, for the admin to see. How would be the easiest way to do this? I know how to make a form, and pull the information into the database.. Any good ideas, plugins or examples?? Thanks

I'm quite new to the DOM manipulation world and I would like to get a head start in order to avoid common errors. I am looking for the most efficient way to manipulate content generated by wordpress using php. At the moment I am using Simple HTML Dom which seems to work just fine.

Also on the side can someone explain what is this syntax (instead of $html this @$html) Thank you very much

When publishing content or changing any settings in the admin, the screen goes blank, I found that it's due to this code in my functions.php file. Is there something wrong with it? <?php if ( function_exists('register_sidebar') ) { register_sidebar(array( 'name'=> 'Footer', 'id' => 'footer', 'before_widget' => '', 'after_widget' => '', 'before_title' => '<div class="title">', 'after_title' => '</div>' )); register_sidebar(array( 'name'=> 'Right-Sidebar', 'id' => 'rightsidebar', 'before_widget' => '<div class="white-bar">', 'after_widget' => '</div>', 'before_title' => '<div class="title">', 'after_title' => '</div>' )); register_sid...
