We have a megathread to help those going hungry. Do we have one for homelessness?

I have no clue how to start a megathread, but I really like how people are banding together to feed each other, and wanted to gather information about how to assist our homeless population, as well.

These cuts to SNAP and public programs and resources are already hard for the housed. For many of the homeless, they could be deadly, especially as winter approaches.

So, any ideas? Any resources? How are we getting through all of this?
