When attempting to create a new user account from a Form Display part, a username is not created in NetCommunity or a sign up request is not generated to The Raiser's Edge.
For Form Display parts, they function differently in regards to sign up requests compared to the User Login part in NetCommunity. When a user creates a new username and password, this creates a "temporary" account for the user to access the form. For the user account to be saved in NetCommunity one of the following conditions will need to be met:
The form has been completed and submited by the user
The form in progress has been saved by the user
If the "Create Raiser’s Edge sign-up transactions" has been marked on the Login option on the form, this will also generate a sign up request to The Raiser's Edge as well.
