Hide last login...

I have been searching for a few days for the code to hide my last login on myspace... I can't find a working code anywhere...

Since we are now unable to edit through safemode or put html in our basic info section, the code for the about me and city section isnt working any longer. It gives the error that the city has to be less than 50 characters and the code that I have is only 45... I have tried it with and without the name of the city and I have tried just putting in 3 characters so it doesn't run over 50 characters but still, nothing.
________________________________________________

The code that I have found everywhere else is this:

<style type="text/css">.lastlogin {visibility:hidden;}

In the about me section
and....
<span class=lastlogin> or
<style type="text/css">.lastlogin {visibility:hidden;}

In the city section under basic info.

Does anyone out there have a working code to hide the last login?
