I would like to display a customized message on top of the "New Site" dialog window, however since it is Silverlight I'm not sure if this is even possible.
I've thought of using javascript to highjack the "New Site" click event from the "Site Actions" menu before the dialog is displayed and show the message here. Then when the user clicks OK open the dialog with the Silverlight control and proceed as normal. But this seems like quite a hack and possibly not worth investigating further. Also it will not work if you create the web through "Manage Site Structure".
Is there an easier way to do this? Like a mechanism in SharePoint similar to how you add custom actions to the site actions menu? The message does not have to be a popup, just some way of displaying custom text as the user tries to create a new web.
"Create"at the top to something custom?
