[cobalt-users] How may I change the creation behaviour of new (v)users

[bib <bib@xxxxxxxxxxxxx>]

Dear all,
Newbe in the managment of Cobalt (RaQ550) system, I did not found any 
documentation about 'vsite' and 'user' managment scripts and the way to 
change theire default behaviour.

For example, on our system, all site have only one user which is also 
admin of here/his site.
We would like to change the way a user or even the admin of a new vsite 
is created sothat she or he may directly upgrade his 'main' site 
location (i.e: /home/site/my.site.org/web) insteed of having to transit 
through, i.e: /home/site/my.site.org/users/john/web).

I found some related config files in /usr/sausalito but no doc anywhere 
about it and I guss I will certainly break my system if I change 
anything there without knowing exactly what I'm doing.

Could you please give me some tips or pointers to documentation in order
resolve this issue ?

Many thanks in advance for your help
Kindest regards
