You can read my letter on LabourList.
Ed Miliband told the Fabian conference this morning that he agreed with the idea of opening up the debate about the manifesto. It will be interested to see what comes of that - and I am sure ideas about how to do it will be welcome.
That might mean what party insiders would call "Warwick III" with a further session to close down the manifesto.
Or it might - as I think - mean a more open process, which tries to put all of this 'learning from Obama' talk into practice, by asking how Labour's manifesto can take forward fairness in the downturn.
The key test is about trust that the offer to engage is real, more than the exact process.
With the party talking about opening up - how should it be done?
UPDATE: This was Ed Miliband's initial response, according to the text of his speech.
Of course, there is more we could do, and in all these areas, our economy, our society, our democracy, we need a manifesto that is radical and transformative and we need your ideas and input.
The Fabians have argued we need to open up the process and I agree.
Next week we will be launching a dialogue on the internet precisely designed to stimulate ideas.
Between now and the manifesto it will be canvassing the best ideas, and a chance for a two way dialogue, so please go to labourspace.com from next Wednesday.
And in many other ways, we need to open out the process and I want to hear your thoughts on this during the course of today.
