Custom Templates - Displaying signup email within profile

(also filed on the civicrm wiki @ <http://wiki.civicrm.org/confluence/display/CRMDOC/Displaying+signup+email+within+profile>)

I've made the following modification to civicrm/templates/CRM/UF/Form/Block.tpl (see below) that allows the primarily email field to be specified in the profile and displayed - without a duplicate as is the case in the demo @

http://demo.civicrm.org/drupal/civicrm/event/register?id=15&reset=1

Block.tpl:

{if $n eq 'email-Primary'} {assign var=n value=email-$bltID}
<td class="label">{$form.$n.label}</td>
<td>{$form.$n.html}</td>
{else}

<td class="label">{$form.$n.label}</td>
<td>
{if $n|substr:0:2 eq 'im'}
{assign var="provider" value=$n|cat:"-provider_id"}
{$form.$provider.html} 
{/if}
{$form.$n.html}

{/if}

With the change made, the email field entry/display that is present in other templates can be commented out. ie.

{*{assign var=n value=email-$bltID}

<table class="form-layout-compressed">
<tr><td class="label nowrap">{$form.$n.label}</td><td>{$form.$n.html}</td></tr>
</table>

*}

Attached are the files that I modified.
