set default login name

i want to set the default login name for user, i.e. each time the user use
the application, the login name would be displayed in advance and user only
need to input the password. how to do that'
million thanks..That depends, is this user creating an account.
Does the username exists already.
Is the username the same for all users or different for each user.
I'm assuming that the user has already got an account, and returning to the
site.
The way you can make the site remember a user is with cookies.
You set the cookie when the user logs in. Then whenever the page loads, it
looks of that cookie exists and if so, sets the users username in the
username textbox
