does this mean, only one user (the owner of a mapset) can create 
new maps in 'his/her' mapset? So if I want another user to have write 
permissions I would have to change the owner of the mapset directory.

for example:

I work in a project (mapset) and during my holliday another user shall 
keep on working for me. If I don't want to create an extra mapset, because 
I will be back in a couple of weeks and don't want to have all data and 
results split in 2 mapsets, I could change the owner of the mapset. Is 
this correct?

ok - I understand, and g.access is only to restrict read and execute 
access (as written in the manual).

yes, that would be fine - I think.

thanks a lot for your notes!
