Just ran across this — IAI runs a mentoring program:
The Mentoring Program matches experienced IA professionals (“mentors”) with practitioners, newcomers to the field, students, and anyone interested in being mentored (“protégés”).
This program is provided as a service to IAI members only. Mentors do not need to be members, but protégés do. If you are not already a member, you can join the Information Architecture Institute to participate as a protégé..
