I cannot get the YouTube embed code to work. It seems to be due to the security issue with Request Validation. I went to the administration guide and it says:

You can enable HTML input on the Membership - User Settings page in the Site admin area, as seen here:

In the user guide it shows antoher check box for Java Script but I don't see that. I also don't see the boxes that contain the allowed tags. However, if I hover over the question mark, then I see that info.

But, when I check the box then try to use the embed code it still throws an exception.

Is this what I should see?

Thanks,
Bob

Oh...
I"m getting this error:
A potentially dangerous Request.Form value was detected from the client (ctl00$mainContent$gallery1$ctl00$txtExternalHtmlSource="<object width="425" ...").
Description: Request Validation has detected a potentially dangerous client input value, and processing of the request has been aborted. This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack. You can disable request validation by setting validateRequest=false in the Page directive or in the configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case.

Exception Details: System.Web.HttpRequestValidationException: A potentially dangerous Request.Form value was detected from the client (ctl00$mainContent$gallery1$ctl00$txtExternalHtmlSource="<object width="425" ...").

Roger this works, but is it a safe thing to do? Thanks,
Bob

Just a quick note about .NET 4: You also need to add this to web.config:

<httpRuntime requestValidationMode="2.0" />
