Forms can be set so that users can choose to "skip" them by selecting the negative statement on a form. This is found on the Form / Settings tab.
Users can select to skip a form by using the drop down menu at the top of the form to select the form negative statement, "I am not interested in ..." and the form will no longer appear in their list of Open Forms.
Once a user chooses to skip a form, the form is still available to them as long as the form is in Active Mode. Skipped forms are available at the bottom of the list of Open Forms. The user can select to show them or hide them.
