Go to Account > User in your SocialHub account for the user administration interface:
Creating users
Click the button to open up a popup where you can specify the name, email address, role and language of the new user.
A confirmation email will be sent to the specified email address. The account will be activated by clicking this link and assigning a password to the user account. Hint: Please check the spam folder of your email program if the email didn't arrive after a few minutes.
By the way: A new user does't necessarily need his own account with the social networks connected to your SocialHub account. Only users who should be able to add a new channel need to be active on the network and have administrator rights on the corresponding account.
Deleting users
To remove a user from your SocialHub account open the options dropdown by clicking the small arrow. Using the "Delete" option will remove the account of the selected person.
