This is not right way.
Setting disabling whisper from admin panel does not work, there is no conditional function in channel.aspx code like this:
<%if(ChatWebUtility.GlobalShowSignoutButton){%>
To disable Whisper only way is to comment out code here:
Is there any functon/method to use with conditional?
<tr>
<td><!-- <select id="select_targetuser" title="tips : Right click to target 'All'" style="vertical-align:middle;width:120px;">
<option value="">[[UI_MENU_TargetAll]]</option>
</select> -->
</td>
<td>
<!-- <input type="checkbox" id="checkbox_whisper" onchange="SetWhisper(this.checked);" /> -->
</td>
<td>
<!-- <label id="label_whisper" for="checkbox_whisper">[[UI_Whisper]]</label> -->
</td>
<td>
<button id="btn_connect" class="ConnectionButton" style="width:92px;height:22px;">[[UI_Menu_Connect]]</button>
</td>
</tr>
