BuddyPress 2.5 introduced some wonderful email functionality. In order to do this, it bypasses WordPress’ default email methods. This means that any filters you applied to the <code>wp_mail_from</code> and <code>wp_mail_from_name</code> filters don’t work with emails sent by BuddyPress. This plugin translates those filters into something BuddyPress can use.

Personal welcome is a WordPress/MultiSite/BuddyPress plugin that lists newly registered users, and allows site administrators to send them a personalised welcome message. The welcome messages are based on templates which you can write yourself (as many templates as you like). Once a message is sent that user won’t appear again.
There are four extra management features:
<ul>
<li>The ability to set all users as having been sent a welcome message (an easy way to bulk remove everyone from the list, for example when the plugin is first installed)</li>
<li>The ability to search for a user and send them a welcome message</li>
<li>The ability to set the new user as being spam</li>
<li>The ability to set the new user and all their blogs as spam</li>
</ul>
Of course, the templates don’t have to be just for welcoming people – they could contain FAQs, help information or anything else.
The plugin also makes use of the __() function to allow for easy translation.
