Problem: New user registers, but never receives their Activation Email – which means they can NEVER log in. And Joomla does not have a way to resend them their activation email.
Solution: wbReactiv Joomla plugin. wbReactiv manually resends Joomla activation email to users who may not have received them yet. It works from Joomla backend and display a
Resend button next to each user who has not yet activated her account.
