Do you support any charities on a regular basis?

I contribute monthly to Habitat for Humanity that helps build affordable housing and Doctors Without Borders which provides free health care in crisis areas around the world. I also contribute financially and as a volunteer to the student housing co-operative I lived in while going to college (the only way I could afford to go to college), which provides affordable room & board to college students with a priority to students coming from marginalized situations, including those who are first in their families to attend college.
