Comment Box. C# , SQL, (should be very cute design)

Comment box design using 'asp.net 4' & 'sql server 2008'. Tool: VS2010. Language:C#,aspx. Database: sql server 2008. I like the comment design of the following web. [login to view URL] Please design it like that. For "leave comment box" design, see the following image. [login to view URL] All the below mentioned requirement is equally important. Read them carefully. 1) Instead of "CAPTCHAs" use the simple idea shown in the above link. 2) When the server-session-variable username == admin, there should be delete button for each comment. This will prevent other users deleting the comments. 3) Flat commenting for users 4) Threaded comment only for admin See the following article which shows the defference between flat & threaded commenting below. [login to view URL] 5) if the admin reply for someones comment, email should be send to that particular person. 6) the profile icons should be randomly selected from a group of icons. But for Admin there should be consistent icon. 7) the max number of comments shown at a time is 20. remaining should be in linked in pages {1, 2, 3.. last} 8) When the server-session-variable username != null, we have to mention the user as premium user (some where on the tab). 9) When the server-session-variable username != null, in the "leave comment box", it should not ask email-ID and username. Instead it should autofill by selecting it from the session variables. 10) the "leave comment box" should be on the top of the design. 11) Various shades of Pink color may be used to differentiate between comments 12) usage of <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> for updating the comment without refreshing the whole page. 13) should be compatible with chrome,safari,firefox,ie. 14) cuteness and sleekness of the design is ultimatly important. ***************************************************************************** Bid with your previous experience relevant to this project.
