Boone Gorges

Requires WordPress 3.0+ Network Mode.
Allows blog administrators to add multiple users to blogs at a time, using only a list of email addresses. When the specified email address matches an existing account, the account will be added as a user on the blog. Otherwise a new account is created and the new user added with the specified role. Based on DDImportUsers.
The plugin determines username automatically from the email address. For example, the email address bgorges100@example.com will produce the email address bgorges100. For that reason, this plugin works best when used in schools or organizations with official, unique email addresses.
When BuddyPress is installed, the welcome email will also include a link to the new user’s Edit Profile screen.
This plugin was developed for Blogs@Baruch of Baruch College’s Bernard L Schwartz Communication Institute. http://blsciblogs.baruch.cuny.edu
