Is there any way to resend a newsletter once it has been sent?
 
It's very inconvient to have to create a brand new newsletter just to make a few changes to send it to a different bunch of users.
 
Anyone?

Easiest way is copy and paste using the clipboard

Or...if you have access to your database, just go into the newsletter table and set the 'Sent' column to '0', then you can send it again.
