Can this be done is CS2007?  I've tried adding this to grouplist.aspx, in the Themes>default>Forums folder, but haven't been able to get it to work.  This may be a completely wrong way to do this, but I'm just guessing here.

 

I added the <%@ Import Namespace="CuteSoft.Chat" %> to the top of the grouplist.aspx file.

 

Then added the code inside the "Who is Online section":

 

 

 

        <CSControl:UserOnlineList runat="server" ShowHeaderFooterOnNone="false">
            <LeaderTemplate>
                <div class="CommonInlineMessageArea">
                    <CSControl:SiteUrl runat="server" UrlName="WhoIsOnline" ResourceName="WhoIsOnline_Current" Tag="H4" CssClass="CommonInlineMessageTitle" />
                    <div class="CommonInlineMessageContent">
                        <CSControl:UsersOnlineData runat="server" Property="GuestCount" ResourceName="WhoIsOnlineView_GuestUsers" />
                        <CSControl:UsersOnlineData runat="server" Property="MemberCount" ResourceName="WhoIsOnlineView_UsersOnlineCount" />
            </LeaderTemplate>
            <QueryOverrides QueryType="AuthenticatedUsers" PageSize="999" />
         <HeaderTemplate>- </HeaderTemplate>
         <ItemTemplate><CSControl:UserOnlineData runat="server" Property="DisplayName" LinkTo="Profile" /></ItemTemplate>
            <SeparatorTemplate>, </SeparatorTemplate>
            <NoneTemplate></NoneTemplate>
            <TrailerTemplate>
   <br /><br />There are <asp:Label ID="lblOnlineCount" Runat="server"></asp:Label> users chatting<asp:Label ID="lblOnlineChater" Runat="server"></asp:Label>.
                    </div>
                </div>
            </TrailerTemplate>
        </CSControl:UserOnlineList>

 

 

But the final sOnlineChatter code causes an error if I try to insert it.
