I think the problem lies in the location of the script: if it is not in the same paragraph, it may appear above, like it does on your site.

@fiys: I don’t really have time to look at it now, but I’ll see what I can do.

in comments my code is:

.avatar{
float:right;
padding: 1px;
border: 1px solid #ccc;
}

{comments_number zero="Comments" one="1 Comment" more="% Comments"}
{if $post->comment_status == 'open'}
<a href="#postcomment" rel="nofollow">»</a>
{/if}

{if $post->ping_status}
{_e text='The <acronym title="Uniform Resource Identifier">URI</acronym> to TrackBack this entry is:'} <em>{trackback_url}</em>
{/if}
{if $comments != ''}

  {foreach from=$comments key=key item=comment}
        {globalvar var='comment' value=$comment}

{capture name=reader}{comment_author_email}{/capture}
var ob_email = "{$smarty.capture.reader|replace:'@':';'}";
var email = ob_email.replace(/;/g,"@");
document.write('');
{comment_text}
	{comment_type} {_e text="by"} {comment_author_link} — {comment_date} @ <a href="#comment-{comment_ID}" rel="nofollow">{comment_time}</a> {edit_comment_link link='Edit This' before=' |'}

  {/foreach}

{else}
	{_e text="No hay comentarios todavia."}
{/if}
{comments_rss_link link_text='<abbr title="Really Simple Syndication">RSS</abbr> feed for comments on this post.'}
{_e text="Deja un comentario"}
{if 'open' == $post->comment_status}

	   {_e text="Nombre"} {if $req != ''} {_e text='(required)'} {/if}
	ID}" />

	   {_e text="E-mail"} {if $req != ''} {_e text='(required)'}{/if}

	   {_e text="<acronym title='Uniform Resource Identifier'>URI</acronym>"}

	  {_e text="Tus comentarios"}

{_e text="Line and paragraph breaks automatic, e-mail address never displayed, <acronym title='Hypertext Markup Language'>HTML</acronym> allowed:"} <code>{allowed_tags}</code>

{else}
{_e text="Sorry, the comment form is closed at this time."}
{/if}

what am i doing bad?

I did get Gravatars working in Blogsome to some extent a while ago, but it exposed the email addresses.
What I’ve done now is obscure the email addresses, and it should be safe to use:
<script type=”text/javascript”>
{capture name=rea…

You need to use smarty tags to obscure the email address, and then use JavaScript to unobscure it.

{comment_author_email|replace:"@":";"}

Takes email@domain.com and turns it into email;domain.com

AuthorEmail = Email.replace(/;/g,"@")

Reverses the operation.

Why do this? The source code will not show the raw email address, and will therefore be safer from Spambots.

Of course, you shouldn’t be using my code at all, as it exposes email addresses.
