freeNas 8 writing, but forbid to delete any files?

[bluecolor]

Hi together,

i'm shortly using free nas, too...and I've got a real big problem...
Is there any possibility, to allow users in freeNas 8 writing, but forbid to delete any files?

Before I changed to FreeNAS I was using Windows Server...
I think, if Windows got this feature, FreeNas will have this, too...i'm shure i'm to close to see it...

Read this carefully. Then read it again. Repeat until you completely understand it. Then admin your system.

I'm sorry. I do not understand.
