Linked in isn´t just a electronic CV, but a place to meet people with the same interests, discussions and also learning something. In the beginning I got to Linkedin because of the CV function, but after some time I learned to appreciate different groups and also used them to discuss or maybe to get a comment.
Here are some of the groups I am a member of:
Coordinators of mentoring programs
International Mentoring Association
European Mentoring and Coaching Council – EMCC
Mentoring – A subgroup of Mentoring at Works
I hope you already find them but if not, go in and look at them right now and become a member.
