Review for Signal Spam by Ray @ Bondi
Rated 1 out of 5 stars
on the surface looks like something I really want, sadly the sign up page in in French with no options to display it in English, sorry France I do not speak your language :)
This review is for a previous version of the add-on (3.0.4).The english version is now available.
