To navigate to the Settings page, navigate to your User Name in the top right hand corner of the screen, then select the drop down arrow next to your User Name, select Settings from the drop down menu.
Once you’ve opened the Settings page, select Users from the options on the left.
Here you will see a list of Users within your current Organisation with some key identifying details. Find and select the User you wish to edit. If you have a number of Users within your Organisation you can use the filter to help narrow down your search.
Once you've selected the user, you will be presented with their profile information. Here you should double check that the Users contact information is correct. Once you've ensured the information is correct, scroll down to the bottom of the popup you will see a RESEND INVITE button, select this button and it will resend the invite email to the listed email address.
