It’s important to consider adjusting a user’s Social Network permissions (or access) because:
A) it allows customer service queries to be ‘auto-assigned’ to the relevant team
B) you may not want every team or member to have access to every social network
C) it’s a required step for posting anything to a social network
D) without it, the network won’t appear in the Social Profile Picked in the Compose Box
