I've raised £200 to Defend sexual freedom for consenting adults.

Organised by Amy Norton
Backlash campaigns for sexual freedom for consenting adults and provides legal support for sexual minorities who are unfairly targeted by outdated and nonsensical "obscenity" laws. Among other things, they have been responsible for getting the ridiculous 'tiger porn case' (look it up) struck down, and for campaigning to get amendments added to the Digital Economy Bill to make it less harmful to consenting adults engaging in safe and victimless fringe sexual practices.
I'm holding a cheap-to-enter writing contest to raise funds for this amazing organisation.
