Joao, Here is a link http://www.analytictech.com/ for software (download version 4 for free) that allows to do network analysis on stored messages. I haven't personally used it yet, but it's been recommended to me by a colleague who is using it for her Carnegie funded project. I also have a document that goes along with the link, but it's too big to be posted to the list, so I'll send it to you directly. Hope this will help you some. ulla ************************* Ulla K.
