First of all, thanks to Write on Finance for including me in the community.
I'm John, and I'm the director of Payday Angels. We're a large short-term lending site, absolutely dedicated to helping people get out of debt and clearly explaining the costs etc.
I spend a lot of time writing for other people's sites as part of our publicity. If you'd like me to write on anything personal finance or economics-related (I have a degree in economics from the University of Cambridge), please just drop me a line.
