This is a quick wordpress tip. If you  are hosting your wordpress on a server  and want to Remove the unnecessary links from WordPress sidebar such as Entire RSS, Commments RSS then follow this steps.

• Go to to your wordpress includes folder and and find widgets.php, it should be at the end
• 
• Open it in any text editor (notepad ++ , smultron) and do a quick search by pressing CMD/WIN + F. This will bring up the find options. The meta block code starts from line 847.
• 
• The code will look like this

• <?php wp_register(); ?>
  <li><?php wp_loginout(); ?></li>
  <li><a href="<?php bloginfo('rss2_url'); ?>" title="<?php echo attribute_escape(__('Syndicate this site using RSS 2.0')); ?>"><?php _e('Entries <abbr title="Really Simple Syndication">RSS</abbr>'); ?></a></li>
  <li><a href="<?php bloginfo('comments_rss2_url'); ?>" title="<?php echo attribute_escape(__('The latest comments to all posts in RSS')); ?>"><?php _e('Comments <abbr title="Really Simple Syndication">RSS</abbr>'); ?></a></li>
  <li><a href="http://wordpress.org/" title="<?php echo attribute_escape(__('Powered by WordPress, state-of-the-art semantic personal publishing platform.')); ?>">WordPress.org</a></li>
