In the hotseat this month is Dawn Austwick, voluntary sector leader and chief executive of the Big Lottery Fund.
Dawn joined the Big Lottery Fund last autumn and has been in the headlines since for her views on social investment, data sharing and the need to create a more adaptive sector. She will be joining us on Friday 24 January from 12.30-1.30pm to answer your burning questions on these issues and more.
You can leave a question for her in advance, and log on over lunch to watch the debate as it happens.
