When I go to log in to this site, as soon as I enter my callsign my name appears in the info box. This is before I even enter my password. Is there any way to prevent this?
Your name appears only after you have entered your callsign and have pressed the NEXT button. It is a feature that allows you to double check that you have entered your callsign/username correctly before entering your password.
Yes, that's correct - after pressing the NEXT button my name appears. I can see the usefulness of that, but I would prefer for it not to show.
