But that's the main page you go to in order to get to all the Social Group features - see the Categories, latest groups, your groups, groups you created, etc.

<if condition="$show['socialgroupslink']">
<tr><td class="$navclass[socialgroups]" nowrap="nowrap"><a class="smallfont" href="group.php$session[sessionurl_q]">$vbphrase[social_groups]</a></td></tr>
</if>
