The list of categories and check boxes does not display properly. The code in OptIn.ascx needs to be changed as follows:

([ = left angles, ] = right angles)

[asp: DataList ID="DSRepeater" runat="server"]
   [HeaderTemplate]
      [table class="OptIn_ListTable"]
   [/HeaderTemplate]
   [ItemTemplate]
      [table class="OptIn_ListTable"]
         [tr valign="top"]
            [td valign="middle" nowrap align="center"]
               [asp:Label ID="Label3" runat="server" Width="70" Visible="False" Text='[%#Container.DataItem("OptInCategoryID")%]']
               [/asp:Label]
               [asp:CheckBox ID="CheckBox1" runat="server"]
               [/asp:CheckBox]
            [/td]
            [td valign="middle" nowrap align="left"]
               [asp:Label ID="Label1" runat="server" CssClass="CategoryTitle" Text='[%#Container.DataItem("Category")%]']
               [/asp:Label]
            [/td]
            [td]
            [/td]
            [td valign="top" nowrap align="left" class="CategoryDesc"]
               [asp:Literal ID="litDesc" runat="server" Text='[%#Container.DataItem("CategoryDesc")%]']
               [/asp:Literal]
            [/td]
         [/tr]
      [/table]
   [/ItemTemplate]
   [FooterTemplate]
      [/TABLE]
   [/FooterTemplate]
[/asp: DataList]
