Sorry for the late reply, was on vacation.
In your case the "anonymous" label is shown to the public (instead of your name) because your privacy settings are set to show your name to logged in members only. Try the following CSS:
/* Hide author name on forum summary only */
#idForumContainer #idForumSummaryContainer div.boxBodyContainer table td.lastReplyTD div.lastReply span
{
display: none;
}
/* Hide author name on forum topic */
#idForumContainer #idForumDetailsContainer #idMessageListContainer div.boxBodyContainer table.forumMessageTable td.left div.boxBodyInfoOuterContainer
{
width: 0px;
}
/* Remove both top and bottom Add Comment buttons on forum topic */
#idForumContainer #idForumPanelContainer input.forumPanelButton, #idForumContainer #idForumDetailsContainer #idForumBottomPanelContainer input
{
display: none;
}
