The Co-operative provides an online community centre for voluntary groups and local activities called Co-operate.
Co-operate offers local organisations a free, permanent platform to which they can add their group, their activities, promote themselves and ask for support. It's completely free. The information about a group is controlled by the group themselves, and they can regularly update their own platform with up to date activities.
For many groups, their page on Co-operate can act like a small website, without any of the maintenance requirements or costs.
