current _user_ documentation?

[Kristian Rink]

Hi all,

I hardly dare to ask, but after some time of playing around with GNUstep, I am 
more or less thinking whether there is any source of more user-related 
_current_ documentation on GNUstep? In example, I am still sort of trying to 
assign applications to file types within gworkspace; the documentation that 
comes with gworkspace or GNUstep in itself didn't prove to be that helpful, 
neither did google.

So... can anyone recommend any sources, or am I into trial-and-error about 
things like that? :)

TIA and bye,
Kris
