I would like to rename or remove the "Sign up for your new account" title but I can't find that anymore in the Properties.

 Well there is the HeaderText="" but this does not replace it it Just adds another Line above it.

If you want to completely remove or rename it I suggest

click on the control until the arrow at the upper right corner appears, then click on the arrow.

click on CustomizeUserStep

then it will display all of the controls in a table

the second <tr> is the label "Sign up for your New Account"

you may change it here and add style if you want -

Customizing does not change anything else with the control, it just lets you see all of the controls, in case you do want to change anything.

If you do not like the create user wizard and want to make your own custom form - I have a posting with code that shows how to make a custom create user using the aspnet_membership and making your own form.

I already figured it out yesterday and I was sorry I spammed this thread. All I had to do was add title tag to CreateUserWizard1 control. Thank you for your help, I will mark your post as answer.
