Let New Users Choose Their Password When Registering
Adds password and confirm-password fields to the WordPress registration form, so new members pick their own password instead of waiting for a "set your password" email.
Snippet Library
Users snippets for WordPress
Snippets for user accounts, roles and profiles: extra profile fields, new columns in the users list, last-login tracking and tighter control of what each role can do. Handy for membership sites, client sites and teams with many authors.
Let New Users Pick an Account Type
Adds an "I am signing up as" choice to the registration form that gives the new account one of the roles you allow, for example Reader or Writer.
Require an Invite Code to Register
Adds an "Invite code" field to the registration form and only lets people sign up with one of your codes, each with an optional limit on how many times it can be used.
