Invited a new user but they've accidentally been deleted or you can't seem to find the email for it? You can simply re-send it instead of having to start all over again.
Note: You must be an administrator of your Ignition account to access this.
First log in to your Ignition account and click on Settings → Users → Click on the user you want to invite.
If you have made and changes to the email address details, you will want to click the three dots → Save & Send Invite, otherwise click Send invite.
This will re-send them an email titled Invitation instructions which will have a link for them to log in and create a password for their Ignition account.
