You may have seen a few bloggers posting about this issue - women are disappearing from UK banknotes and we're being encouraged to sign the petition in protest and blog about who you'd like to see on a banknote.

Leave a link if you've posted about this, would love to see some more suggestions. If you're tweeting it's #banknotes
