Family and friends of Rosie Choueka will meet this week to discuss plans for setting up a charity in her name.
The mother-of-two moved thousands with her blog about battling breast cancer before she succumbed to the illness last week.
Mrs Choueka, 38, from north-west London, captured the nation's hearts with an emotional final post, in which she appealed to readers to "please remember me".
This week a close family friend said they had been "overwhelmed" by messages of support for Rosie's wish to have a charity set up in her name.
Husband Elliot said that he planned "at the appropriate time" to give well-wishers details of his wife's desire to establish a charity in her memory.
