In the postbit template, find this and delete it:

                <if condition="$post['rank']"><div class="smallfont">$post[rank]</div></if>

And move it to here (in red):

            <td nowrap="nowrap">
                <if condition="$post['rank']"><div class="smallfont">$post[rank]</div></if>

                <div id="postmenu_$post[postid]">
                    <if condition="$show['profile']">
                    <a class="bigusername" href="member.php?$session[sessionurl]u=$post[userid]">$post[musername]</a>
                    $post[onlinestatus]
                    <script type="text/javascript"> vbmenu_register("postmenu_$post[postid]", true); </script>
                    <else />
                    $post[musername]
                    </if>
                </div>

That should put it below the avatar and above the username. If using the postbit_legacy template, do similar (the <td> tag is a bit different in the postbit_legacy, but the username stuff is all there).
