***** To join INSNA, visit http://www.sfu.ca/~insna/ ***** Dear Socnetters, Many thanks concerning the answers to my question on virtual community and social network. They really helped me. I have another question, but this time, it concerns the links (or relations) between people in a social network. What allows us to link an actor to an another actor ? For instance, the fact that they have already been in touch, the fact that one of them has sent a mail to the other, the fact that they have a similar profile, etc. ? Thanks in advance for your help, Regards, Emilie Marquois _____________________________________________________________________ SOCNET is a service of INSNA, the professional association for social network researchers (http://www.sfu.ca/~insna/).
