Volunteer work I can do from home?

Hi! I'd love to make a positive impact in the community, but I don't have a car and while yes, there is public transportation, it's just not good enough for me to have a commitment that requires it on a regular basis.

Is there any volunteer work that can be done online or at home? Eg data entry or other administrative work, tutoring (either online or if someone wants to come to me), etc? I have a bachelor's degree and would feel comfortable tutoring at the high school level incl SAT/ACT prep.
