Question Hide region name / WorldGuard

Hello everybody,
I'm german. Sorry for my bad english...

My problem:

I installed WorldEdit and WorldGuard on my Server. Both are working. I defined a region and saved it with the /safe command. Now, every time when I enter this region, the name of the region is shown in the chat. But not only for operators. Every player can see this.

I want to hide this for normal players. Or if it's not possible: For every player.

Thank you for your help!
