Other listservs
The mentoring-related projects at NWREL host many listservs and discussion forums for practitioners in the field:

EDMentoring Forum
The EDMentoring Forum is a listserv designed exclusively for Office of Safe and Drug-Free Schools mentoring grantees, and membership is restricted to representatives of that group. Additional information about the EDMentoring Forum can be found on the MRC website here: http://www.edmentoring.org/grantee/listserv.html.
CNCS Listservs
The Corporation for National and Community Service (CNCS) operates many listservs that are of interest to mentoring, tutoring, and volunteer programs of all types. A full listing of CNCS-sponsored listervs, and rules for posting on them, can be found here: http://nationalserviceresources.org/email-lists
