                    Hello guys,
For a project I'm working on, I need to verify that the users are listing websites they own.
I've a custom field for the URL, and I'd like to ask for verification adding a file on the website or a <meta> tag in the header of the pages. 
Does anyone implemented something like that before?
Thanks!
