right Ellen , but we have to distinguish between doing it for free and it is free. Servers cost money from the hoster, electricity is not free, hardware costs money, everything with the network costs money (ip, bandwidth, provider) there are taxes on everything to list a few components. Let's take the OSGrid as an example (as so often) that is financed by donations other grids are also financed by donations or the owner(s) pay for it for us. The many regions in the grids are paid for by the region owners. Free .. a thank you is probably free
