[support] Need to change user login

[Roger]

Using latest Drupal 7 fully updated.

I need to change the user login system.. Change the title of the 
Username to 'Question 1' and the Password title to 'Question  2'
Is there a way to do this please.

Also, user names and passwords will be based on a series of questions 
and answers. Is there a way I can get ddslideshow or views-slideshow to 
randomly read one one line at a time from a text file rather than create 
a content type and a lot of entries in the content system.

Thanks in advance
Roger
