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.
