Juvenile Court Volunteers/Probation Program "http://www.cookcountycourt.org/" is a site of the court. and there is an mentoring program provided. So it is not that detail. There is a volunteer involvement opportunity but for the donors there is hard to contact. not that much links
Here's a link to the Mentoring Network on this web site. It provides good information but because it is so deep within the overall web site, it's not likely to attract much attention, or much support from volunteers. This is an example of a program which would benefit from setting up a space on ning.com to talk just about it's mentoring activities.
