.comUserStatCaption {font-weight: normal;}
.comUserStatus {margin-left: 2px; margin-top: 10px; color: #2F5376; font-weight:bold; font-size: 10px;}
.comUserRank {margin: 2px;}
.comUserRankText {font-size: 10px;font-weight:bold;}
.comUserRankImg {border: 0px}
.comUserName {}
.comUserImg {margin: 2px;}
.comDate {font-weight: normal; font-style: italic; font-size: smaller}
.comDateCaption {font-weight: bold; font-style: normal;}
