Simple Free Plugin
Summary : Download, Install, activate and it works. The way plugins should be! This user activation plugin will be installed on everyone of my networks.
For those of you running a WordPress multisite network it is a real pain when a user doesn’t receive their activation email. It takes two days for it to clear by itself or you have to go inside the database within the _signups table then either clear that users record or activate that user by changing activated from 0 to 1.
Not only does this take way more time than it should but what if you have someone managing your site for you? You don’t want them inside your database and you surely don’t want to have to pay someone qualified to work within databases to clear unconfirmed sign ups.
So I was digging around today for a solution and found a free plugin that worked perfectly called Unconfirmed here: http://ronsmart.com/links/unconfirmed
Unconfirmed makes life a lot easier managing your sign ups. Just install the plugin, network activate it. Go to users within your network admin and you will see Unconfirmed. Then simply click the resend activation email link or just activate them and you are done.
I hope this plugin works as well for you as it does for me. When I found Unconfirmed I stopped my search. If you know of a better or comparable solution I would like to know more about it below.
