I can customize the footer of the welcome email coming from SharePoint when a user is added to a site by editing the data name="ServerEmailFooter" element in core.en-US.resx. The question is, can I get anything dynamic in there, like the email of the owner who added the user, or any owner of the site?
So far I've seen <GetVar> and <ListProperty> used in the resource file, but no idea how to figure out which vars are available.
