I think there is a need for an effective collaborative knowledge system within the community projects sector. Wikipedia is a good model, but a system like this needs to be as friction-less to use as possible. Especially since a lot of people working on these projects will be volunteering their time, there is a need to minimise the overhead of such a system to encourage usage. Something worth talking about with these groups.
As an aside, I think a lot of benefits can be had from integrating "social movement" with "social eating". Moving together has a history as long as eating together and I believe its impacts on social connectedness are undeniable. This could be as simple as going on walks together, group movement classes or less restrictive sessions (something like "open movement to music"). When discussing social prescription in the context of mental health I think social movement is essential. I do think many activities in Foodhall do fulfill this (gardening together, cooking together, cleaning together, DIY together...), but I think there is a benefit to considering it in a more direct way.
