To add a new user to the Denim Social app, go to Administration > Users > Create User

From there, you will be able to fill in the necessary fields for that new user.

Regarding setting the password, this is optional, however what is recommended is to have your new user go to app.denimsocial.com and hit the "forgot password" function so they may set their own password

*Note: Make sure you are seeing the correct user role and timezone for each user.
