Web link that would include a page variable

Yes, but if the URL contains a username I need to populate the username field. The URL; view.mysite.com/my.policy?input_1=user1 would populate the input_1 web site field and also allow the user to enter a username manually. Yann's idea may be a step in the right direction if I use 2 logon pages, one using his solution and another that has the username field visible and allows a user to enter a name manually.
