Say goodbye to the headache of managing users in a multisite network! Now when a user visits a blog in the network, the user will be added to the blog with your specified roles automatically.
Here is how this plugin works:
<ol>
<li>When a user visits a site, this plugin checks if the user is already a member of the site.</li>
<li>If the user is a member, do nothing.</li>
<li>Otherwise add the user to the site with the user\’s role in blog #1, or a role specified by you. [Sync Role]</li>
<li>If the user is not an existing member of blog #1, the user will be added with a role specified by you. [Default Role]</li>
<li>When a user\’s role is updated, the user\’s new role can be updated across all the bogs the user is member of. [Role Update]</li>
</ol>
