I use ProNavy theme and I want to add the 3rd column there . Here's the code:

.footer_out {
	background:#0F0F0F url(images/pronavy/footer_bg.png) repeat-x top
}
.footer {
	text-align:left;color:#fff;width:910px;margin:auto;padding:6px
}
.footer_box {
	padding:12px
}
.footer_h2 {
	font-size:1.3em;color:#fff;margin-bottom:6px;margin-left:2px
}
.footer_h2_bottom_1 {
	border-top:1px solid #555
}
.footer_h2_bottom_2 {
	border-bottom:1px solid #111;margin-top:-2px
}
.footer_h1 ul {
	list-style-image:url(images/pronavy/tick.png);margin-left:0
}
.footer a {
	color:#D9D9D9;text-shadow:none
}
.footer a:hover {
	color:#19579E;text-shadow:none

and here's footer template:

<tr>
<td class="footer_box" width="50%" valign="top">
<div class="footer_h2">{$mybb->settings['bbname']}</div>
<div class="footer_h2_bottom_1"></div>
<div class="footer_h2_bottom_2"></div>
<div class="footer_h1">
<ul class="footer_h1">

</ul>
</div>
</td>
<td class="footer_box" width="50%" valign="top">
<div class="footer_h2">Links</div>
<div class="footer_h2_bottom_1"></div>
<div class="footer_h2_bottom_2"></div>

</ul>
</div>
</td>
