title: How to remove block from magento left panel?
body: <p>I have changed magento signup page layout from <code>1column.phtml</code> to <code>2columns-left.phtml</code> in <code>customer.xml</code>. I need to display only one block on my magento Signup page left panel. All other blocks should be removed from the page. Currently I am getting three magento's default blocks on my left panel with my custom block.
  How to remove other blocks using xml?
  Anyone Please help.</p>
