Verify Email Addresses of New Users
Sends new members a confirmation link and blocks them from logging in until they click it, which keeps fake and mistyped email addresses out.
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.
