[x.alliedmods]

This is the code that must be modified :

<table id="post$post[postid]" class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="0" border="0" width="100%" align="center">
<tr>
	<if condition="$show['announcement']">
		<td class="thead" style="font-weight:normal; border: $stylevar[cellspacing]px solid $stylevar[tborder_bgcolor]" colspan="2">
			<img class="inlineimg" src="$stylevar[imgdir_statusicon]/post_$post[statusicon].gif" alt="$post[statustitle]" border="0" />
			<phrase 1="$post[startdate]" 2="$post[enddate]">$vbphrase[x_until_y]</phrase>
		</td>
	<else />
		<td class="thead" style="font-weight:normal; border: $stylevar[cellspacing]px solid $stylevar[tborder_bgcolor]; border-$stylevar[right]: 0px" $post[scrolltothis]>
			<!-- status icon and date -->
			<a name="post$post[postid]"><img class="inlineimg" src="$stylevar[imgdir_statusicon]/post_$post[statusicon].gif" alt="$post[statustitle]" border="0" /></a>
			$post[postdate]<if condition="!$show['detailedtime']">, $post[posttime]</if>
			$post[firstnewinsert]
			<!-- / status icon and date -->
		</td>
<br />
		<td class="thead" style="font-weight:normal; border: $stylevar[cellspacing]px solid $stylevar[tborder_bgcolor]; border-$stylevar[left]: 0px" align="$stylevar[right]">
			&nbsp;
			<if condition="$show['postcount']">#<a href="showpost.php?$session[sessionurl]p=$post[postid]&amp;postcount=$post[postcount]" target="new" rel="nofollow" id="postcount$post[postid]" name="$post[postcount]"><strong>$post[postcount]</strong></a></if>
			<if condition="$show['inlinemod']">
				<input type="checkbox" name="plist[$postid]" id="plist_$postid" style="vertical-align:middle; padding:0px; margin:0px 0px 0px 5px" value="$post[checkbox_value]" />
			</if>
		</td>
	</if>
</tr>
