You can join a 'gift economy' platform 'Impossible' co-founded by Lily Cole and Kwame Ferreira here.
They want to disrupt monetary exchange with altruistic reciprocity so money is ranked along with violence and sexual conduct as no-nos at the site. Sounds great, but I have visited Impossible a few times and found the offers and requests disappointing. I think this proves that Impossible is simply 'gift exchange' not really a 'gift economy' where production is part of a gifting or non-monetary system too.
On the up side at least it's a useful experiment and the platform is open source and self-managing, following Wikipedia.
