Michael Portillo (at approx 20:15) on R4 "Any Questions" was dismissing the number of complaints to the BBC and suggested Mumsnet (because of having a lot of e-mail addresses) might have 'suggested' members complain to the BBC.
I for one had no such e-mail from Mumsnet, and I suspect there is never any suggestion of sending requests to members to act in a co-ordinated way, while there may be information about campaigns (distinct difference) and why MNHQ suggests a specific campaign is worth supporting.
I feel it would be worth someone high profile at MN listen to the piece (on the East Enders storyline) and consider whether it would be worth commenting about this specific suggestion made on national radio and implying that if Mumsnet doesn't like something it would 'organise' thousands of 'individual' complaints.
I think you really ought to set the record straight, that MNHQ picks up on views and may sometimes consider a campaign but does not 'muster support' with a secretive mass e-mail to do such things as individually complain to push up numbers.
