I am using List workflow on Document library using Sharepoint designer Foundation 2013(2010 Workflow Platform).
I want to assign task individual task to each member from Sharepoint group. Is it possible? If yes then how. Please guide.
Yes, this is possible.
When setting up the Group you need to ensure the setting 'group membership is viewable' by 'Everyone' (not just the members) to ensure the WF can read the group members.
Once done you can then assign a WF task to a Group name opposed to an individual
