Find the SHOWTHREAD template,
In there you'll find:
<!-- controls above postbits -->
Inside that section of code, find:
Code:
<td class="smallfont"><a href="newreply.php?$session[sessionurl]do=newreply&noquote=1&p=$FIRSTPOSTID" rel="nofollow"><if condition="$show['closethread']"><img src="$stylevar[imgdir_button]/reply.gif" alt="$vbphrase[reply]" border="0" /><else /><img src="$stylevar[imgdir_button]/threadclosed.gif" alt="$vbphrase[closed_thread]" border="0" /></if></a></td>
After that, add:
Code:
<td class="smallfont"><a href="newthread.php?$session[sessionurl]do=newthread&f=$foruminfo[forumid]" rel="nofollow"><img src="$stylevar[imgdir_button]/newthread.gif" alt="$vbphrase[post_new_thread]" border="0" /></a><else /> </td> <else />
<td class="smallfont"> </td>
This is what the section looks like on my template:
Code:
<!-- controls above postbits -->
<table cellpadding="0" cellspacing="0" border="0" width="25%" style="margin-bottom:3px">
<tr valign="bottom">
<if condition="$show['largereplybutton']">
<td class="smallfont"><a href="newreply.php?$session[sessionurl]do=newreply&noquote=1&p=$FIRSTPOSTID" rel="nofollow"><if condition="$show['closethread']"><img src="$stylevar[imgdir_button]/reply.gif" alt="$vbphrase[reply]" border="0" /><else /><img src="$stylevar[imgdir_button]/threadclosed.gif" alt="$vbphrase[closed_thread]" border="0" /></if></a></td>
<td class="smallfont"><a href="newthread.php?$session[sessionurl]do=newthread&f=$foruminfo[forumid]" rel="nofollow"><img src="$stylevar[imgdir_button]/newthread.gif" alt="$vbphrase[post_new_thread]" border="0" /></a><else /> </td> <else />
<td class="smallfont"> </td>
</if>
<if condition="$show['pagenav']"><td align="$stylevar[right]">$pagenav</td></if>
</tr>
</table>
