An OTBKB wrote in to say:

I’m interested in getting involved in a volunteer
organization based in Park Slope or the nearby neighborhoods.  I particularly
like groups dealing with:  women, kids, the arts, animals.  Do you have a good
resource for Brooklyn-based volunteer opportunities?

If readers have ideas please let me know. I will compile them and post on OTBKB. Send as a comment or to louise_crawford(at)yahoo(dot)com.
