[JMEWLS`]

	<div class="postdetails">
		<div class="userinfo">
		  <div class="username_container">
			<vb:if condition="$post['userid']">
				{vb:raw memberaction_dropdown}
				{vb:raw post.onlinestatus}
			<vb:else />
<span style="font-size:larger;">{vb:raw post.musername}</span>

			</vb:if>
		  </div>
