from admin you will navigate to builders and pages builders, you will then look at profile builder, the list will come up wtih the nickname block on there, you may not be able to rename it, but you can try, i think it crashes the dbase if you change the name of the block. i think you have to create a new block, but how you are going to make it bind to the password is another story, but you can give it a try. hope this remedial answer helps you at least get started.
