mumsnet why don't you allow petitions on other boards?
Because people get annoyed with petitions clogging up the other conversations - now obviously some are very worthy and important - we too think this one is, hence us making it a discussion of the day.
However there are plenty of petitions online that are very specialist or localised "stop Mr Jones at number 23 parking in front of my driveway"
(NB this is an exaggerated example for comic effect)
While these are no less important to the people who have started them we prefer MNers to post petitions in one section to keep things easy to navigate.
HTH
