Ever wanted to send email to all Mozillians in a region, or the results of some other mozillians.org search? Perhaps if you are thinking of launching a local initiative?
Mozillians doesn’t have that feature, but now you can. If you install my handy Greasemonkey user script in your browser, every page of Mozillians search results will have an “Email All” button at the top. It will also have an “Email Vouched” button, because it seems the search will let you search for only unvouched Mozillians, but not for only vouched Mozillians :-|. So the code does the filtering for you. It should work in all UI languages, but bug reports are welcome.
(Note that Mozillians does search results page fetching on demand, so if you want to email everyone matched to a search, make sure you scroll to the bottom of the page first and make sure it has loaded them all.)
