Site Review

To get a better understanding of .NET I decided I would practice by writing a web board in .NET with C#. I have all the pieces done, but I am worried about possible security holes that could be accessed for evil intentions. I was wondering if people could check it out and see if they could find any security holes. And I am always taking any suggestions and constructive critisicm to improve the site.

AlvinTurn the ViewState off on the forum and thread list repeaters/datalist .. You might have to screw around with the login form at the top, but you will be saving a lot of payload to the clients if you can turn it off.

I am writing a forum for one of my sites, and I saw my page payload size go down from 80k to about 20k just from turning off the viewstate on the thread list
