I've found a problem when validating links that have been submitted with an incomplete URL. For example;

If a user submits this as their url:
newurl.co.nz

instead of:
www.newurl.co.nz

in the admin area, when you go to click on the 'validate' link to view the submitted site, it puts in...

http://www.mydomainname.co.nz/cgi-bin/newurl.co.nz

...as the link to validate. It it simply a matter of checking the submission? It would then have to cover ftp, http, https etc too though I guess.

Cheers,

Regan.
