Rss icon near every forum except no-guest forum

[RedFoxy]

Hi all!
I wanna ADD an rss icon in each forum row, i do it adding some html code in forumhome_forumbit_level2_post and forumhome_forumbit_level1_post (see below), but now i wanna add the permission to don't show the rss icons in the forums that are not viewable to guest user...

If you look at http://www.softairmania.it/forum you can see the rss icons in each forum, included the private forums, how can i do?

my templates modifications are:

Open: forumhome_forumbit_level1_post

Find:
<table cellpadding="0" cellspacing="0" border="0">

In-Line Find:
>

Before ADD:
width="100%"

Find:
<td>
<div>
Replace WITH:
<td style="width:100%">
<div>

Find:
</tr>
</table>

Add BEFORE:

<td style="vertical-align: top">
<a rel="nofollow" href="$vboptions[bburl]/external.php?forumids=$forum[forumid]"><img src="images/rss/rss_feeds14x14.gif" title="RSS del forum: $forum[title]" alt="RSS del forum: $forum[title]" border="0"></a>
</td>



Open: forumhome_forumbit_level2_post

Find:
<a href="forumdisplay.php?$session[sessionurl]f=$forum[forumid]"><strong>$forum[title]</strong></a>

Before ADD:
<div style="float: right">
