I just started a new column for ASP.NET Pro: ASP.NET Under the Hood

In the first edition, I answered a reader's question about dynamically applying themes based on user profile settings at runtime. You can check out the column here: http://www.aspnetpro.com/features/2006/02/asp200602mb_f/asp200602mb_f.asp

If you have other questions, don't forget to send them my way and if I write about it in the column, of course I will also answer you personally in the process.

Cheers!
