This is a very good initiative . However this app could be way more useful if you allow users to post what they have to offer too so project owners can search around to find items which they need for their project. Currently we can only select projects to contribute to and the number of users and projects are just a couple. I have alot of recyclables to post but none of the projects are asking for those. In the end I gave up and just use carousell instead. If this app could improve , it can bring a lot of like minded people/organizations together to up cycle more items and make the environment a better place.
