Hi, I am completely a newbie and I've got a work that I cant get through. A friend of me had asked me to put an extra input field of "ID" in the login form, so, that every user will have to provide their ID also in order to login to the website. I thought it would be easy but now when I've looked into the wp-login.php file, I think I surely need some expert advice for that. (as i cant understand it)
Please tell me if there's such plugin or something. Or if some expert can just help me out by giving a code. Any kind of help will be highly appreciated. Thanx in advance.
