Allow Multiple Accounts
Allow multiple user accounts to be created, registered, and updated having the same email address. By default, WordPress only allows a specific email address to be used for a single user account. This plugin removes that restriction. The plugin’s settings page (accessed via Users -> Multiple Accounts or via the Settings link next to the plugin on the Manage Plugins page) provides the ability to allow only certain email addresses the ability to have multiple accounts (such as if you only want admins to have that ability; by default all email addresses can be used more than once). You may also specify a limit to the number of accounts an email address can have (by default there is no limit). The settings page also provides a table listing all user accounts that share email addresses (see screenshot). Compatible with Multisite and BuddyPress as well. Links: Plugin Homepage | Plugin Directory Page | Author Homepage Template Tags The plugin provides three optional template tags for use in your theme templates. Functions Returns a count of the number of users associated with the given email. Returns the users associated with the given email. Returns a boolean indicating if the given email is associated with more than one user account. Arguments $email (string) An email address. Filters The plugin exposes three filters for hooking. Typically, customizations utilizing these hooks would be put into your active theme’s functions.php file, or used by another plugin. c2c_count_multiple_accounts (filter) The ‘c2c_count_multiple_accounts’ hook allows you to use an alternative approach to safely invoke c2c_count_multiple_accounts() in such a way that if the plugin were deactivated or deleted, then your calls to the function won’t cause errors in your site. Arguments: same as for c2c_count_multiple_accounts() Example: Instead of: Do: c2c_get_users_by_email (filter) The ‘c2c_get_users_by_email’ hook allows you to use an alternative approach to safely invoke c2c_get_users_by_email() in such a way that if the plugin were deactivated or deleted, then your calls to the function won’t cause errors in your site. Arguments: same as for c2c_get_users_by_email() Example: Instead of: Do: c2c_has_multiple_accounts (filter) The ‘c2c_has_multiple_accounts’ hook allows you to use an alternative approach to safely invoke c2c_has_multiple_accounts() in such a way that if the plugin were deactivated or deleted, then your calls to the function won’t cause errors in your site.

Network Mass
This plugin allows for network administrators on WordPress multisite environments to send an email to users that they select based on the users’ roles in individual sites. For example, checking only “editors” will go through each active site and add anyone with the role of “editor” to your list of emails to send to. To use the plugin after installation & activation, find Users / Mass Email in the network admin dashboard in your multisite install. Then, select the user types you wish to email and click on the button for “Load the List”. This will load the list of users to email. Then you may compose your email in the boxes provided and click the send button at the bottom of the screen. If all goes well you will be presented with a confirmation page indicating that your email was sent successfully. This plugin is NOT intended for administrators to be sending unsolicited spam to their users. In fact, it was created with more formal environments in mind. One example would be a University setting where administrators of the network may need to notify students and faculty of potential downtime. With the plugin’s implementation I would imagine it would be a highly inefficient way of sending spam anyway.
