Hey,
I noticed that on the two registration pages:
http://www.dotnetfunda.com/users/login.aspx?ReturnUrl=%2fdefault.aspx
http://www.dotnetfunda.com/users/register.aspx
And the edit profile page:
http://www.dotnetfunda.com/users/register.aspx?username=rtpHarry
The validators only have an error message of "*" (except the country selection drop down).
It's pretty obvious what you have to put in them but it could confuse people if they dont notice the * right over on the far side of the screen...
