Engender Health, a fantastic DIA client doing work on worldwide reproductive health access (a key indicator of gender equality from Maine to Myanmar), jury-rigged this nifty use of tools to make a "send a complimentary copy of our e-newsletter to your friend" page.

The page prompts visitors to enter their friends' name and e-mail. It's actually just a sign-up page (though the page doesn't opt friends into Engender's e-mail list) associated with a trigger, which trigger happens to contain the most recent e-newsletter content. It does require a manual update of the trigger content with each new e-newsletter, but it's a nifty instance of the user appropriating existing functionality to create what amounts to a new tool in the system.
