This page looks can be done by DNN itself without other plugin.

How can I do this? Does anybody help me?

...but how to you align the top required arrows with the actual form field? (it does when I cut-and-paste, though...strange?)

User Name: Enter a username User name is required

First Name: Enter a First Name First name is required

Last Name: Enter a Last Name Last name is required

Display Name: Provide a Display Name Display Name is required

Email Address: Enter a valid Email address

It looks like the dotnetnukecorp site has plenty of room in that module, so I wouldn't expect it to wrap like that...especially on a dotnetnukecorp site. :) ...always the top that wraps and never the bottom.
