I had emailed the developer of Mail Scripts (currently 1.3.7) about helping me with an AppleScript to automate the deletion of email in Mail. After a couple emails I am now helping him beta test his new versions of Mail Scripts, 2.0.
Beta testing software is great, especially if it helps you do work faster. I have beta tested Path Finder for some time now, and have contributed much to its design and functionality. Path Finder is another product that helps me save time.
Mail Scripts 1.3.7 are a set of AppleScript's for use with Mail and Address Book. They work pretty well. With the upcoming 2.0 scripts, they will now have a UI because the developer, Andreas Amann, has rewritten them using Panther's Xcode Tools, Interface Builder, and AppleScript. This makes these scripts into small applications, and makes them much easier to use.

Add Addresses - You can add multile addresses to Address Book. This, like all the scripts, reads the messages that you have selected and gathers the names and email addresses from the To, From, CC, and BCC (I think) fields.
Archive Messages - You can archive and export messages. Export options are to text or mbox format. You have the choice to narrow your archive/export by date, read status, and flagged status. The archived emails go into a newly created mailbox folder Archived Messages (Date Archived). This is very handy to me as I am archiving by month a lot of my mailboxes, such as my Sent box.
