How to make <strong> on user not guests in (forumdisplay_thread)

[Jay99]

I found the answer I was looking for.

In case someone else is looking for the same fix, here it is......

<if !$thread['threadusername'] then>
{$thread['profilelink']}
<elseif $thread['uid'] == 0 then>
{$thread['profilelink']}
<else>
<strong>{$thread['profilelink']}</strong>
</if>

This works perfectly.
