I have just recently moved down from Manchester, where I was involved with the Oxfam campaigns group there.
It's quite different to the shop network as the emphasis is more on raising awareness on Oxfam issues i.e Fairtrade, health and education etc. through campaigning, petitioning etc. I was hoping to find a similar kind of organisation in Sheffield. I will venture out to Glossop Road to have a look for the office. Thanks for links and contact numbers
