How can you best volunteer?

If you know someone who lives alone ask them to join NextDoor, which is Facebook for neighborhoods. It helps them stay in touch with those right around them. Vital in a crisis.

I am not familiar with that project, but I would trust David’s judgment in such matters.  How else can people volunteer usefully, especially if they do not wish to leave their homes?  Keep in mind that useful volunteering is also a good way to keep people occupied and at home!

Please do leave your suggestions in the comments.  if nothing else, even “placebo volunteering” could be highly worthwhile.  I will put up some of the best ideas in a later post.
