There are 2 ways you can invite colleagues. One way is to go to your homepage and click on the 'person with a +' icon, which is next to the notifications bell.
When you click on that icon, a popup box will appear that says 'Invite your colleagues to belongly.' You will then type in the invitee's information in the sections below. Please make sure to hit send.
The second way to invite colleagues is to go to your homepage, and you will see a 'People you know' section on the right side of the page. With that section, you will see the 'invite your colleagues' at the bottom.
When you click on that button, a pop box will appear. You will then enter all of your colleague's information in the sections below. Once you've finished, please be sure to hit send.
