Your new Workspace won't be complete until you involve other people to work with.
This can be done in a couple ways; you can either add a coworker's complete profile under the member management tab, or you can simply copy and paste a list of email addresses or phone numbers to invite them to your workspace to setup their profile themselves.
To do that, click on the "Invite People" link on your dashboard, or the "Send Invitation" menu on the left side of your screen.
If you have a just few coworkers that you'd like to invite to collaborate with you, you can send them an invitation to setup their profiles in your Workspace by entering their email address or mobile number (see left image below).
If you have a larger amount of people you'd like to invite, click on the link below that says, "Do you need to send more invitations?" You'll be brought to the bulk invitation page (see right image above) where you can enter many more email addresses or phone numbers separated by a comma.
Once you click send, your coworkers will receive an email or text message with a link to set up their profile. This can be done on either a computer or mobile device.
