So the idea is to use iMacros to auto-visit linkedin profiles.
Two scripts are available :
linkedin-auto-visits-groups.js
To visit people profiles of members belonging to a group
and
linkedin-auto-visits-people-search.js
To visit people profiles from the result of a reasearch you made.
Don't forget to go in the People menu element before copying the URL.
The scripts are originally comming from: https://github.com/LeCoupa/kgh-imacros
