The Forum Text-In Code feature allows non account users to text in Issues to a meeting.
A unique code needs to be entered when activating this feature. This code or phrase, goes into the blank box in the Advanced Settings. A user texts that code to Phone number: 1-321-766-5599.
Any user that uses the forum text in feature will be automatically added as a placeholder user on your account. They will not be added to your invoice or be able to login to your account. For more information on placeholder users, see this article: User Management - Add, Delete and Restore
An alternate option for any users that are part of your account already, add them as meeting attendees into a specific meeting so it does not create duplicate users on your users list, and have the user setup the main text in feature: Creating and Removing Texting Actions for People Headlines, Issues and To-Dos
For any non members of your account though, the forum text in feature would be the only option where they could submit issues.
To activate the Forum Text-In Code feature:
At the conclusion of the meeting, remove the code and click Save.
