I had a dream (sorry ,Martin L-K) that Ofcom finally dumped all 0870's.
Then I realised the serious implications :-  There would be no 'sayNo to 0870' site anymore - what a nightmare.  Nowhere to vent one's spleen and rail against Ofcom, the Gov, greedy Companies, etc.
Where will we all go? How will we spend our time?

Then I woke up and realised we are fighting the equivalent of a blancmange and so needn't even think about winning!!  Normality reigns.

But would the site need to be re-named??
"SayNoTo 0844/0845/0871 etc " doesn't have the same 'ring' to it.   
No doubt some of our greatest minds are already working on this problem!!
