Sidebar is just substitution supported HTML. You can put whatever you want. Example as follows.
Code:
<ul class="kpost-profile">
<li class="kpost-username"><a rel="nofollow" title="" href="index.php?option=com_comprofiler&task=userProfile&user=[user_id]&Itemid=47" class="kwho-admin">[cb:userfield field="formatname"/]</a></li>
<li class="kpost-avatar"><a rel="nofollow" title="" href="index.php?option=com_comprofiler&task=userProfile&user=[user_id]&Itemid=47" class="kwho-admin"><span class="kavatar">[cb:userfield field="avatar"/]</span></a></li>
<li>[cb:userfield field="onlinestatus"/]</li> <li class="kpost-userrank">[cb:userfield field="forumrank"/]</li>
<li class="kpost-userposts">Posts: [cb:userfield field="forumposts"/]</li>
<li class="kpost-karma">Karma: [cb:userfield field="forumkarma"/] [karmaminus] [karmaplus]</li>
</ul>
