Validation Message | Remove red asterisk - how to?

When questions are validated, by default, validation messages are enabled. On the survey header, the message: Questions marked with a * are required will show up. You can edit this message if desired.

Go to: Surveys (Select Survey) » Edit » Design

Under the design tab, click on Display Settings

Here, you can change validation message and settings. Validation Message setting is enabled by default. You can switch it off if you don't wish to display the message and the red astrix by default. Validations will still work, only the messaging will be disabled.
