Every time you come here you will see a randomly selected mutual aid link someone has submitted to the Fairshare.help bot.
If every one who comes here just gives a little to whoever's request comes up for them there /\ then in time everyone will get something and if enough people do that then everyone will get what they need.
If you have more to give / are feeling generous, here is a randomised list of others you can give to. Work from the top-down and give what you can to as many people in need as you can and encourage others to do the same.
