[drupal-docs] Permissions page

[Karoly Negyesi]

Hi!

We need docs for some permissions...

What the heck is "post comments without approval", really? Is it useful  
for anonymous users? Authenticated users? Or it's something for those with  
super cow powers? "create url aliases" that's fine, but can I change them?  
I guess others can find some other questions, but I think these proves my  
point.

Regards
