Well, you can do that by editing the template, I believe. If you for example wanted it right after the username column, just find this in the memberlist_resultsbit template:

	<td class="alt1Active" align="$stylevar[left]" id="u$userinfo[userid]">
		<a href="member.php?$session[sessionurl]u=$userinfo[userid]">$userinfo[musername]</a>
		<if condition="$show['usertitlecol']"><div class="smallfont">$userinfo[usertitle]</div></if>
	</td>

And under it, put something like this:

<if condition="exec_switch_bg()"><td class="$bgclass">$userinfo['rank']</td></if>

I haven't tested it as I'm not using ranks at my forums at the moment, but it's basically just a variation of the code used for all the other columns so it should work.
