From my post of 16.12.2010
Perhaps Rowan / team at MNHQ could come up with a briefly worded piece as a reason for this campaign to "have legs" and submit it via the Suggest a Campaign page on 38Degrees.
38Degrees has an e-mail submission facility so a user can identify their location (and thus their MP) and then get a pre-written e-mail (which they are then encouraged to edit, so they can add examples from their own locality), and then submit.
It means that the general sentiment will be the same from potentially thousands of people but tailored to specifics from their lives.
Clearly there's no point reinventing the wheel, so the first step would be to get 38Degrees to adopt this as a campaign.
Once that's done, it would surely just need a mention in the MN newsletter and in some topic areas, to make MN users aware of this e-mail facility, so they could put forward to their MPs the widely held views that there's no need for these mags to be made as visible as they are.
"Modesty covers" (sealed plastic bags with slogans overing photos) on all of them would mean a standard method of dealing with them could be requested, so whatever shelf they ended up on, they should cause less offence.
It does not go to the level of banning them completely which some may argue for, but surely it would be a 'reasonable' first step, and would mean any obnoxious newsagent would have the bags already in place so despite placing them on unsuitable shelves, would have 'lost that battle' with parents who dislike the smut being visible.
